I downloaded the PJSIP stack pjproject-1.0-rc2 from www.pjsip.org and built it using Carbide. I am using S60 3rd edition emulator software for loading and running the same.

I have not made any modification to the PJSIP stack.
The call setup i am trying to make is as follows

s60 on PC1 <---> PC3 Running registration server <---> s60 on PC2

When I do make a call, the SIP signaling goes through fine (I got to know this cause i captured packets using ethereal). However, the next part, i.e. the transfer of audio, is not happening.

Can you please let me know
If any modification is required to get the audio part working?
If not, what else is required?

Thanks for your help....
