Hello Sunil, I checked it the offer/answer of this call and unable to find anything like that....
The only thing i have noticed which uttam has mentioned that the SSRC are different for both the RTP packets which is going from SBC and the one which is coming to SBC... Below is the SDP information in UDP format.... could you please help me out on this.... or i am not sure why it is giving the two SSRC value in same dialog...
