Using SIP with voice data stream?

    Hello,

 


    I am working on a project to 
grab an incoming raw voice data from a socket and redirect it to another machine 
using SIP which machine will in turn redirect the voice stream to a client 
program which will utilize and listen in on the voice data. ; I have not 
been able to find any code samples of anyone trying to work with voice data and 
SIP and was wondering if anyone here has seen or run across or knows of any code 
samples or projects that have used SIP with voice data. ; If you do please 
let me know so that I might be able to learn from it.  I know that SIP Communicator uses and can make voice 
calls using SIP, but finding the code I need has been a difficult task and not 
straightforward.  If someone can give me some guidance in this area I would 
be appreciative as well. ; Thanks.

Hello Merrick Fonnesbeck,
  
 
  
Media streams over Internet are not accessed directly by sockets. We are using abstraction above internet socket called "RTP". The sip-communicator (and other sip phones) uses a package called "JMF - Java Media Framework" to handle the media streaming.
  
 
  
To read the implementation in sip-communicator you may look at:
  
net/java/sip/communicator/impl/media/MediaControl.java
  
net/java/sip/communicator/impl/media/CallSessionImpl.java
  
 
  
We at www.siptele.com are doing such applications for competitive fee.
