With MizuPhone you can connect to any SIP server (softswitch/proxy/registrar) on the public internet or on your local area network.

 

MizuPhone purpose is to combine the SIP compatibility with Peer to Peer intelligence relying on an intuitive user interface. It is fully interoperable with most of the VOIP service providers, VOIP software and hardware (workstations, notebooks, PDAs, IP-Phones, etc). Mizu-Phone is highly optimized, it doesn’t consume your system resources and it doesn’t disturb you when you’re working. When you use it for HD quality video calls, it can take advantage of multi-core systems.

Quick Start

dial.PNG 

                Login to the softphone with profile username/password. If you are a first-time user, click on the "New user" label and enter any username/password. This is not your SIP account info, it is there to be able to separate multiple users on a single computer (in an internet coffee for instance). On your home PC or laptop you can check ‘Remember my password’ checkbox to have your data introduced automatically the next time you log on, and check ‘Login automatically’ to automate that too.

                Once logged in, under File / Basic Settings menu choose Accounts. Introduce your account name in the first field. The second field is for the domain on which the service runs. Introduce here the IP address of your SIP service provider, followed by a colon (:), and the sip port number used (5060 by default).  Introduce a username/password in the fourth and fifth field that is going to be your SIP account. The ‘Use this account checkbox’ serves to separate the used accounts from not used accounts. Click Save. When you are connected, the message Connected appears on the lowest line of the MizuPhone window in green. Otherwise you will see the corresponding error status in red.

You can connect to multiple VoIP servers at the same time by introducing more accounts.

Note: for customized softphones the SIP username/password needs to be entered on the main login form. All other settings are usually preconfigured by your service provider.

                Once the client is registered to the VoIP server, you can start to initiate and receive calls or other activities (fine-tune your settings, add contacts, start video calls, start conference calls, send file, send chat, etc)

 

 

Functions

Starting

MizuPhone can be started in multiple ways:

·         Started automatically with windows. Click on the MizuPhone icon on the bottom-right corner of the desktop

·         Use windows start menu or double-click on the desktop icon

·         Pressing Ctrl+Alt+M

·         Click on a browser hyperlink. Example: <a href="sip:4444@domain.com">call displayname</a>

·         Double click on a file with .sip extension. The file must contain an URI or it has to be a configuration file.

 

Login

Depending on your version, the login username/password can mean the followings:

·         Username/password to protect your local profile

·         Mizutech username/password (for free Mizutech SIP server and profile storage)

·         Username/password for your VOIP provider sip server

 

If you don’t already have a Mizutech account, click on the “New user” link and enter your username / password. If the “Create Mizutech account” checkbox is not checked, only a local profile will be created to protect your configurations and history from other users on the same computer.

If you use the softphone on your private computer, you can check the “Remember my password” and the “Login automatically” checkbox, but if you use it from a public place, make sure, that these checkboxes are cleared and always click on Menu -> File -> LogOff when you are finished.

Change the language for your needs (currently English, Swedish, Russian, German, Romanian and Hungarian is available) and hit the “Login” button to begin.

Once you’re logged in, the word ‘Connected’ will appear in green on the bottom of the application window, and the text Available will appear in the lower left corner of the application window (by default you are available but you can change that with a click on the little triangle left to the ‘Available’ text).

 

Voice calls

You can initiate voice calls in multiple ways:

·         Right click on a contact and choose “Call”

·         Click on the green call button

·         Click on a phone number’s link to begin a call to the selected number (this is useful when a contact has more than one number)

·         You can configure to call the contact when you double-click on it (the default double-click action is chat message)

·         From the Menu -> Action choose Call

·         Switch to the Dial tab, and enter a phone number or username.

You can also enter the full URI. E.g.: username@address:port, where the username can be a phone number too. The address can be a domain name or an IP address. If the port is missing, then the default port is used which is 5060 for the SIP protocol. On the dial tab you can quickly select your last called numbers from the phone number drop-down list.

When a call is initiated (or on incoming calls), the call tab will appear where you can see important information about the call such as contact panel, caller ID,  call status,  ring and call timer, disconnect reason and transfer status if any. Right click on the contact or click on the Action button to do more actions when you are in call, such as: send DTMF, hold the call, transfer the call, add more participants (conference), add video, etc.

 

Instant Messaging


You can initiate instant message (chat) sessions in multiple ways:

·         Right click on a contact and choose “Send Chat”

·         Click on the chat icon on the contact panels

·         From the Menu -> Action choose Send Instant Message

From the Chat tab you can select the desired number (if the selected contact has more than one) and the preferred sip server (if you are connected to more than one sip server). After this, you can send plain or formatted (html) message to your peer (depending on your configuration, default is html). You can insert emoticons and set text color and style too.

 

Video calls


When already in call, right click to the contact and select “Add video”. There are lots of video codecs to choose from. Make sure to fine-tune your preferred video bit rate to achieve the best possible quality. You can make even HD quality calls if you have enough hardware and bandwidth.

 

contacts.PNGConferences

When you are in a voice or chat session you can always add more participants to the session.  The conference is handled by the softphone local mixer, so you can speak with other people even if your VOIP provider doesn’t support conference. The standard SIP conference protocol is also supported, so you can be invited to such conferences too.

 

Contacts

Contacts can be easily added, dropped, renamed, imported or exported from Menu -> Contact. To see and edit a contact profile, click on the “Details” link or double-click on the contact photo. When a new contact is detected (by presence or automatic neighbor discovery) you will get a confirmation form when you can accept or deny the presented people. If somebody spams you, you can easily put it on the blacklist and you don’t receive any more messages from that person. To force a neighborhood discovery, click on Menu -> Contacts -> Find People near Me. If you have many contacts you can put them is separate groups (Menu -> Contacts -> Create new Group)

 

File sending / sharing

Right click on a contact and select “Send file”. You can send files only to other MizuPhone users, but the protocol is compatible with every SIP server (the sip server will see an ordinary call only with a special codec).

You can configure a shared directory on your computer in Settings -> Misc. Your contacts can access this file in an easy way. To access other contacts shared files, just right-click on the contact and click on Shared Files. If this option is not available, than the contact doesn’t have shared files or doesn’t use MizuPhone.

 

Remote desktop

For an easier collaboration you can use the ‘Remote desktop’. Right click on a contact, select “Remote Desktop” and you will be logged in on your contact PC. You can work on your peers desktop remotely. This feature is enabled only between MizuPhone users but it is compatible with every sip server (the sip server will see an ordinary call only with a special codec).

 

Send / Receive Faxes

You can receive fax images by setting an account as a fax channel. In this case, the calls will be treated as faxes (no local ringtone is generated; the incoming fax messages are stored in the predefined fax directory converted to pdf). To send fax messages, select Menu -> Actions -> Send Fax, or, alternatively, you can mark some users as being fax devices (check the ‘Is Fax Device’ checkbox the User details/ More tab); in this case, when you right click on the users, the “Send Fax” option will appear. Click on it, select the fax image (bmp or tiff) and push the “Send” button. For a good free tool to create FAX images, please check PDFCreator. After you install it, you can print any document in FAX format (Configure PDFCreator to Save as TIFF G3 fax encoding with EOLs)

 

Voicemail

MizuPhone supports the voicemail related SIP RFC’S, and additionally implements local voicemail functionality. Voicemail can be configured at File Menu -> Settings -> Voicemail. Check the “Show advanced settings” checkbox to see more options here. You will be notified when your servers has new voicemail messages if the “Remote Voicemail” option is set to “Auto” or “Yes”. For the local voicemail to work you have to set your greeting sound and the circumstances when voicemail will be activated (always, on busy, etc).

 

Call forward

The call-forward functionality can be set on the “Voicemail” section. Just specify the phone number(s) if you want your calls to be forwarded (always, on busy, etc). You can be notified by missed calls/IM messages if you activate the “send missed calls/messages to my email address” checkbox. In this case, you need to specify your email address correctly for your profile, because notification messages will be sent to this address (File Menu -> Edit your profile). Additionally you can accept incoming calls automatically by filling the “Auto accept call from” edit box.

 

Other Tasks

For a complete set of communication channels, there is also a built-in quick link to your email client. Just right click on a contact and press “Send Email”. Alternatively, the embedded email client can be used to send emails. You don’t need to have a working email client in order for this to work. You can also send SMS messages to mobile phones. SMS messages are sent like chat messages, but the number of characters is limited to 160 and the format is always plain text.

 

Scripting

The scripting module can be installed as an Add-On.

Any external programs can be launched or controlled in response to MizuPhone events. In this way MizuPhone can be easily integrated with CRM application or can handle useful tasks. For example you can ring to your home number and an action can happen, like a video camera being started automatically.

There are more than 15 events predefined like call start, call stop, dtmf received, etc. You can write any command launchable from windows command prompt.

There are a couple of predefined keywords which will be replaced to their meaningful value when applicable, like xusername, xcaller, xcalled, xduration etc. You can launch an embedded webpage like this: “embedded www.mywebpage.com?params...”

If you want a webpage to be displayed for every incoming call with the callernumber as a parameter, like www.mycrm.com?phonenumber=123456, you have to do the following steps:

1.       Install the scripting engine (Tool menu -> Add-ons -> Scripting -> Install)

2.       Go to the scripting configuration (File menu -> Advanced Settings -> Scripting)

3.       Check the “Enable” checkbox

4.       Set the “In call start” value to www.mycrm.com?phonenumber=xcaller

5.       Clear the other unneeded settings

From now on, your webpage will be displayed with every incoming call, with the caller number as the parameter.

 

Routing

You can explicitly set the exact name/number and the used sip server (if you have more than one) at every call. However if you don’t specify these settings, the softphone will automatically guess the best sip server for your call based on your call history and the called prefix. You can also type a complete URI (number@address:port) instead of a name. In this case the call will be routed through the server specified by address:port. The address part can be a domain name or an IP address. You can also control the dialed number by the Dial Plan (File / Advanced settings / Dial Plans).

MizuPhone can send the initial INVITE (Sip message) to multiple addresses where a contact can be. It always remembers the contact’s last location, so even if your SIP server is down, you can still call your contacts. For proper RTP routing the softphone will automatically detect your network, nat and firewall and will try to pass them correctly using various technologies (firewall control, UPNP, STUN, ICE  and other proprietary methods). When the remote party RTP port is not obvious, it can start to send the RTP stream to multiple locations, and will choose the one from where it receives answer.

Application

Under ‘Application’ menu there are the settings related to application behavior under windows. To make the program start whenever the computer starts, check the checkbox ‘Automatically start with windows’. Check ‘Associate with callto: links’ to make the program handle all SIP links (auto launch the softphone when you click on a SIP URI), check ‘Auto detect new versions’ make this application automatically search and install newer versions. Check ‘Allow multiple instances’ to start 3-4 or more instances of the program, all running parallel and each logged in with a separate username and password. If you check ‘Optimize CPU load’, than the program will run more efficiently lowering its priority while in the background and increasing the priority while you are in a call. By checking the checkbox Trace to file, all logs will be saved to a file. You can set different levels of logging in the ‘ Trace level’ list from minimal to max log level including RTP log. To have a view at the current activity of the application press ‘View logs’ button. To see all the logs in a text file press ‘Open Current Log file’ button on the bottom of the log window. You can close this window with the X mark on the top right corner. In the ‘People detect’ list set the way you want the application to handle new people found on the local network. Set the minutes after which people see you idle in the next text field at “Show me idle after x minutes of no activity”. If you check ‘Publish “Speaking” status while on the phone’ checkbox, the speaking status will be sent to your contacts while you are on the phone. To automatically add the numbers you talked to your contact list check the next checkbox: ‘Auto add dialed numbers to my contact list’. You can specify what event will happen on a double click on a contact in the next frame ‘On contact double-click’, with the options ‘Last action’, ‘Start a call’, ‘Start chat’ or ‘Do nothing’. In the next frame, ‘Advanced manual configuration’ a key and a value can be set on a list of modules. This is for expert users. Click on ‘Set’ button when you’re finished.

 

3accounts.PNGAccounts

The ‘Accounts’ menu is for handling your SIP account information. Choose an account in the ‘Account’ list, or add a new account with the ‘Add new account’ button. You can delete accounts with by selecting them and pressing the ‘Delete’ button. Introduce any name you like in the first text field ‘Account name’, introduce the domain address into ‘Domain’. This has usually the form domainname:sipport, or ipaddress:sipport, where the sip port is by default 5060, don’t change that unless your SIP service provider tells you to do so. In case when a different proxy server needs to be used, introduce the proxy address into ‘Proxy Address’ text field. The username and password that you specify in the next two text fields are the SIP username and SIP password, not your external login data. ‘Auth UserName’ have to be used when your private and public username is different.  Check the checkbox ‘Use this account’ to use that account, if this is not checked it won’t appear at login. You can also load settings from a template file in the next text field with the ‘Load’ button.

 

 

 

 

 

 

 

4dial plans.PNGDial Plans

This menu makes it easier to use prefixes. In the first frame, ‘Number rewrite rules (global)’ are the prefix rules defined by you. Introduce the original number or prefix in the first text field, introduce the prefix you might want to remove from the beginning of the phone number in the second text field, and / or the suffix you want to remove from the end in the third text field, and/or add a prefix to the beginning of the phone nr. in the fourth text field,  and / or add a suffix to the end of the phone number in the fifth text field. Click ‘Add’ to add the modified phone number  to the list in the next text field, or select one and press ‘Delete selected’ to delete it. In the next text field, ‘Routing preference for the selected account’ you can add phone numbers or prefixes for the selected account above. Again, delete these if you want with the ‘Delete selected’ button.

 

 

 

 

5network.PNGNetwork

The local network related settings are presented on this page. Introduce a local IP only if there is a multi-home configuration, force this IP only in that case, otherwise leave the default ‘auto detect’ setting. Change ‘Local Domain’ only if you’re told to do so, otherwise leave the default setting. The local signaling port is set by the application at start, again change it if you’re told to do it, and otherwise leave the given port. ‘Local RTP Ports’ is the range of RTP (media) ports set by the application. Usually only the first 2-4-6 port will be used in the given range. The next 8 checkboxes make the NAT traversal easier and improve the functionality of the program. ‘Enable STUN’ will enable a part of the application based on the STUN protocol (STUN stands for Session Traversal Utilities for NAT).

‘Enable rport’will enable rport, a part of the program that works based on RFC 3581. The Session Initiation Protocol (SIP) operates over UDP and TCP, among others.  When used with UDP, responses to requests are returned to the source address the request came from, and to the port written into the topmost Via header field value of the request.  This behavior is not desirable in many cases, especially, when the client is behind a Network Address Translator (NAT).  Rport defines a new parameter for the Via header field, that allows a client to request that the server send the response back to the source IP address and port from which the request originated.
-’Enable UPNP’ enables the UPnP architecture, if your router has support for it.
-’Enable ICE’ will enable ICE, a protocol published in RFC 4091 (the acronym stands for
Interactive Connectivity Establishment, developed by the IETF Internet Engineering Task Force). Check this checkbox to make NAT traversal easier.
-’Auto QoS’: this will enable the automated Quality of System.
-Check checkbox ’Silence Suppression’ to eliminate computing capacity wasted on parts of a conversation, when there is only silence transmitted.  
-’Cache DNS records’ – this will store the DNS records.
-‘Signaling packet loss concealment’ –will conceal packet losses in signaling.

Jitter is the delay with which a delayed packet comes, measured in milliseconds. By default this is set to 30-300 at will change its size dynamically based on your network conditions. Increasing max jitter may help, if the voice quality is poor.

You can set on which protocol ports to listen in the ‘Listen on’ frame. UDP is the most efficient protocol for SIP. A click on the ‘System settings’ button shows the windows network properties window, and you get some NAT help if you click on the ‘Firewall / Router Guide’.

SIP Settings

Under SIP settings menu you can set everything related to the SIP protocol. The checkbox ‘Register interval’ and it’s value to the right set the time interval at which REGISTER messages are sent to the server. ‘Presence interval’ and the value to the right sets the interval at which presence information is sent to the server. If you check ‘Use Publish’, your presence and contact information will be sent to your SIP server using the PUBLISH method. Check ‘Enable session timer’ to measure the time spent in conversations. If you have more telephones or communication devices logged in with the same ID check ‘Allow forked requests’ and an incoming call will ring on all the devices logged in. The first device to answer takes control of the incoming call. Check at ‘Auto mute inactive calls’ to silence calls that arrive while you are in a conversation. Check ‘Keep alive interval’ to let the application send keep-alive messages, the default value of 25 seconds is sufficiently dense. You can set the keep alive message too in the ‘Keep alive message’ frame, to the values: Auto, Empty line or Notify. Under SIP Settings menu you can find the security settings, in the ‘Security’ frame, check the checkboxes ‘Use blowfish and compress’, ’Encrypt signaling(TLS)’, ’Encrypt media (SRTP)’, and ’Only encrypted sessions’ to increase the security of your conversations. The most convenient default protocol is UDP, but you can select other settings, in the ‘Default protocol’ list. Click ‘Save’ to save your settings.

7compatibility.PNGCompatibility

You should use these settings if you have signaling or media related issues with your VoIP server.

 Select Basic only/Extended/Non Standard/All from the Allowed headers list. The signaling address and the media address (IP addresses) can be set for the followings: always force public address, use public address when possible, auto detect whether to use private or public address (this is default), use private address when behind NAT, and always force private address. The default setting for ‘Address in SDP has priority’ frame is dynamic, but you can set it to “has no priority” or “has priority always”. Check the checkbox ‘Allow forked media’ to enable the softphone to initiate multiple media streams on call start.

FAQ

 

I can’t receive incoming calls

If you use a NAT or firewall that cannot be handled automatically by MizuPhone, you can explicitly set the listening SIP and RTP ports on the softphone, then configure your device (router, NAT or firewall) to route the requested ports to your softphone (setup a virtual server configuration). You usually have to route the default SIP port (5060) and some RTP ports (for example between 50000 and 50005). And, of course, you have to be registered on your SIP server(s).

 

How can I get the best voice quality?

The best quality built in codec is SpeexUWB (speex ultra wideband), but in order to be used, your peer must also have this codec. PSTN calls don’t have wideband codecs, because of their characteristics. For this codec to work properly, you will need a quality 45 kbits upload and download (29 kbits for raw codec payload + rtp and udp payload + some signaling). To achieve the best quality, you must use a headset. If you hear noise, enable noise suppression. If you hear cutting voice, check this FAQ.

 

The voice quality is bad. How can I improve the voice quality?

Enable the silence detection.

Increase the jitter buffer.

Use a low bandwidth codec (for example iLBC).

Make sure that some other program doesn’t consume all of your CPU time!

Make sure you have at least 10 kbits/sec upload and download.

 

How to call other UA directly? (Bypassing the sipserver)

Switch to the Dial page.

Enter the “phone number” in the following format:

username@domainname:port

for example:

myfriend@192.168.0.5:5094

(if you omit the port, the default port will be 5060)

 

How to monitor SIP messages?

Set Setting->Application->Trace Level to “Details”

Eventually you can install a network sniffer (for example Wireshark) and set to the port to local signaling port.

 

How to clear my saved login password?

When you check the “Remember my password” checkbox, your password will be saved.

To delete the saved password, just click on File menu -> LogOff (for example when you leave a public internet location)

 

I would like to use only a certain codec

Go to File Menu -> Settings -> Codecs (activate the “Show advanced settings” if you don’t see codecs).

Set the priority for your codec to the lowest value. (0=highest priority, 100=lowest priority)

Eventually you can disable all other codecs (uncheck the “Use this codec” checkbox; but in this case, calls may fail if the remote endpoint don’t have the selected codec)

 

What is my profile?

Your profile means your data, settings, contact list and history archives.

You need to protect these data if you share your computer with others or when using MizuPhone from a public location.

With MizuPhone you can protect these sensitive data with a username and password which is requested on the login form.

Enter any username and password and your data will be encrypted and safe.

In customized softphone versions the username and password you enter on the login form will automatically be used for authentication by your service provider.

Your profile can be stored on a public server, so when you sit at another computer your settings and contactlists can be downloaded and you don't have to type it again.

If you don't need this feature, than just check the "Login automatically" checkbox to get rid of the login form.

 

Where can I store my profile?

Your profile can be stored on a public server, so when you sit at another computer your settings and contactlists can be downloaded and you don't have to type it again.

With Skype, MSN, Yahoo, etc this thing is very obvious, but with MizuPhone you are free to choose your provider(s) and your central profile location, so it will require a little time to set-up, but it is more secure

If you don't have access to such a central storage location, then create a free Mizutech account because Mizutech will give your profile storage on their servers for free.

Your profile is encrypted except when using advanced XCAP storage option, when the server will manipulate your profile and thus it cannot be encrypted by default.

 

Microphone volume is not saved?

It is not saved when you modify the volume during the call (it will be applied only for current call)

But you can modify permanently from File Menu -> Settings -> Devices

 

Sometimes the phone dials the same number twice

This is because the softphone tries to initiate the call on multiple paths with different via branch. And it seems that the other end cannot handle separate via branch correctly. You can disable this from File Menu -> Advanced Settings -> Sip Settings -> uncheck the “Allow forked requests”

 

How to change my account?

You can just logoff from File menu and enter the new login username and password.

When a headset is connected via the Audio port on the computer, the computer doesn’t ring at incoming calls

You can control the ringer device from File Menu -> Settings -> Devices.
