[sip-comm-dev] problems with two simultaneous calls.


#1

Hi,

I'm using sip-communicator in my Master's thesis, but I experience some problems which I do have some troubles to overcome. I'm not certain whehter my problems are due to a bug or if I use sip-communicator in a way it is not supposed to. This is the case:

I start by establishing a call from one SIP ua to another (both sip-communicator), voice only. Now, because of mobility, service discovery and geographically positioning, one of the SIP uas get notified that it is possible to establish a new session to another device capable of receiving video as well as voice. While keeping the ongoing voice session, another (simultaneous) session is initiated towards this new, higher capability device. The SIP messages are sent perfectly fine, but when the media flow is about to be initiated, the sip-communicator gets an MediaException. This is the provided stacktrace:

net.java.sip.communicator.media.MediaException: Internal error! AVTransmitter failed to find a format's corresponding ipAddress
    at net.java.sip.communicator.media.AVTransmitter.createTransmitter(AVTransmitter.java:337)

    at gov.nist.javax.sip.EventScanner.run(EventScanner.java:310)
    at java.lang.Thread.run(Unknown Source)

The console output from sip-communicator is enclosed at the bottom of this mail.

I hope I was able to describe my problem in a understandable manner. My question is if whether the problems I experience is due to a bug in sip-communicator, or if it is due to my untraditional use of the software? I would appreciate any clues pointing my in the direction on how to solve my problem. I have tried to look into the source code myself, but my knowledge of JMF and media handling is rather limited.
