SIP Voip implementation For ECF


Session Initialization Protocol(SIP) is an Application Layer protocol which supports many services such as VoIP, IM, Presence Information and etc. But currently it's widely used for applications based on Voice calls and Video Calls.Eclipse Communication Framework is consists of many protocol implementations such as XMPP, YaHoo, MSN and etc. And also it contactins providers developed based on the above protocol implementations. Hence my goal is to implement a provider for VoIP for ECF based on SIP protocol for ECF.


  • SIP Provider for ECF
  • RTP Provider for ECF
  • SIP Related tests
  • Relevant Documentations and User Guides.


Time line for project Milestones is given below

Project Code Base

Currently the project code base is hosted at & Google code site.

Check site how to access the repository via git.

The Google Code is at

This code base is managed using Sub version version control system.

Now this codebase is hosted at [] as well. New improvements and features will be added to this new repository.

Path is: call/sip/modules.

Running Test Cases

 Since this is a VoIP provider, to test functinalities you need to have at least 2 participants. You may use a Remote Sip Softphone or a Sip Echo service as the remote participant. 

I have created 5 sip accounts for ECF testers and following are the credentials for those sip accounts. You need these credentials to initiate calls, register your softphone and to recieve calls.

Account 1

Name: Eclipse ECF Sip Tester 1

Special SIP service Uri

  1. To test audio sessions, set remote participant to , you should hear some music playing
  2. To test microphone, set remote participant to, you should hear your echo back

You need to use one of these account to Initiate the ECF SIP softphone.

You can find the Testing guide at . Follow the instructions there for successful testing.

  • The Sip Provider uses port 5060 and FMJ RTP provider uses port 6022, 6023.
  • Make sure that there are no other services are running on these ports.

New Features
