Java VoIP Library Description

v.8.2 is available     

The Mizu Java VoIP SDK (JVoIP) is a compact and flexible SIP library which consists of one single jar file of ~2 MB and it can be used in many ways:

  • java VoIP library: add VoIP to you java app (or any JVM based) or create your own Java VoIP SIP client
  • standalone VoIP desktop application: as a compact convenient dialer as a Java SIP Softphone
  • console/command line VoIP: flexible java SIP client for any automation with endless configuration capabilities
  • VoIP applet: embedded to your website (you can create a custom HTML/CSS design and access from JS)

Cross platform: runs on all OS with Java SE support (Windows, Linux, MAC, others).
It can be used directly from any JVM language such as Java, Kotlin, Closure, Scala, Groowy, JRuby or Jython.
The API can be accessed from: Java, JavaScript or any others via UDP, TCP or HTTP (clear text, URL, JSON, XML).
Compatible with all SIP server, softswitch or IP-PBX such as Asterisk, Freeswitch, FreePBX, Cisco and others.
The settings can be specified from: API, command line, config file, URL or sent via SIP signaling.

With this Java VoIP SDK you have a full featured SIP/media stack in a single jar file, easy to integrate or embed into your desktop or web java application. Create your custom java voip client, integrate it with callcenter software or embed in VoIP devices such as IP-PBX or gateways so users will have a fully functional VoIP softphone without the need to download any other third-party software. You can create your own custom SIP client, java softphone or use it to add VoIP call capabilities into any software not directly related to VoIP (such as games or CRM’s) or to perform any kind of VoIP automation (auto dialer, auto answer machine, etc).

Example

 //Include the JVoIP.jar to your project (both the package and the main class are named "webphone")
import webphone.*;

//Get a webphone instance
webphone wobj = new webphone();

//Set parameters (replace uppercase words)
wobj.API_SetParameter("serveraddress", "VOIP_SERVER_IP_OR_DOMAIN");
wobj.API_SetParameter("username", "SIP_USERNAME");
wobj.API_SetParameter("password", "SIP_PASSWORD");

//Initialize the sip stack
wobj.API_Start();    

//Make a call (replace DESTINATION with a SIP username, extension, phone number or SIP URI)
wobj.API_Call(-1, "DESTINATION");

//You can also register, accept incoming calls, send chat message and perform other operations.
//Download a working example from here: Java SDK Test.
//See the documentation for more details.
