By using encrypted VoIP transport users will be able to communicate confidentially and your VoIP traffic cannot be sniffed and blocked by third party agencies or corporate firewalls.
    Mizu VoIP tunnel is a special VoIP server software whose task is to encrypt all communication from/to the clients and to forward the calls to your server(s) using the common SIP protocol. This UDP level encryption will not add any overhead to your network traffic and can work completely transparent.  
    Several ISPs, Telco’s and countries like Dubai or Oman are filtering VoIP or degrading the media in order to force a consumer to use their own VoIP or traditional PSTN services. Using Mizutech built-in encryption you can forget all about these issues. These solutions can work in VoIP networks provided by Mizutech or can be seamlessly integrated in your network without any configuration change in your existing servers.
    The encryption will allow VoIP usage in any countries bypassing all kind of VoIP filtering (unless srtp encryption which can be easily detected by VoIP filters)


Included softwares and services:

• Tunneling server (including backup/failover server when needed)
• Customized softphone with built-in encryption
• Customized webphone with built-in encryption
• Client tunnel (can be used with other softphones)
• Server setup by our support for no extra charge (for this please provide a remote desktop access for our support team)
• Integration with your existing infrastructure (including balance and rating display on clients)
• Free support; no recurring payments
• Free trial period (pay only if you are satisfied)

Benefits:

• Proven solution: used by well-known telecom companies with success suppressing any VPN, VoIP Tunnel (VPS) or Voice guard solution
• Works with your existing VoIP servers. The tunneling server is using the standard SIP protocol (all major RFC's and drafts) and has proven compatibility with all existing devices on the market
• Work with any ITSP and service provider
• Full integration with any VoIP server, (Voipswitch, PortaBilling, Asterisx, Trixbox, Cisco, etc)
• Credit and balance display on the clients + direct links to your website (new user registration, tariff listing, etc)
• Fast startup: start using encrypted VoIP in a few hours after contacting us. No changes are needed in your existing infrastructure.
• Communication in all scenarios, i.e. for making and receiving calls from blocked areas e.g. Dubai in UAE or Oman
• Built-in registrar server, sip proxy, IM/presence server and b2b sip stack
• Reliability: our servers are used on enterprise environments where high uptime is a must
• No quality loss: by using UDP transport level encryption, all the negative impacts of traditional VPN solutions are bypassed
• Maximum call completion rate and maximum voice service duration
• Secured communications between clients
• Very difficult ISP detection
• Strict call path protection and security up to termination
• Both the signaling and the media is encrypted
• High throughput: up to 6000 simultaneous call using one server instance
• No network overhead. Excellent voice quality without any latency and performance compromise. Unlike other TCP based VoIP tunneling solutions, our server can encrypt UDP packets transparently
• High speed encryption/decryption: fast proprietary encryption or standard based (tls, srtp)
• Multiple proprietary encryptions: fast encryption with symmetric keys or using blowfish cipher + packet compression
• The tunneling server can offload a huge traffic from your server(s) by handling all the communications between the clients (voice, video, presence, chat, etc) and forwarding only billed traffic to your server
• Easy-to-use, easy to integrate and cost-effective with zero configuration and maintenance. No network or firewall modification is required. All authentication requests and billed calls (e.g. calls to PSTN) can be forwarded to your server like they were  before.
• Runs on standard hardware: Windows server is required (preferable Windows server 2003 or 2008)
• Load balancing and failovering:  the Mizu tunnel can send the traffic to multiple server using different routing algorithms
• VoIP over HTTP: perfect solution to bypas firewalls in corporate networks (both signaling and media tunneled as a HTTP stream)
• Automatic failowering from the fast UDP protocol to a bit slower HTTP tunneling which is almost impossibile to be blocked (this is especially useful from behind corporate firewalls where all UDP communication can be blocked)
• Custom features if needed
