Nitin,your understanding is wrong here. Uttam's concern was that, there could 
be two different incoming RTP streams to your SBC with different SSRC value, if 
thats the case then you need to see why the destination point is behaving in 
odd manner?Regards,Ayyanar Original message From:Nitin Kapoor<

Two Media Stream in one DialogTo: Uttam Sarkar Uttam,You are correct...i 
checked the the SDP, and unable to find multiple mlinesinto it, as well as the 
RTP stream source and destination ip and port isalso same...The only thing i 
have noticed that the SSRC are the different in both theRTP packets which is 
going from source and which is coming fromdestination....Could you please tell 
me, what could be the possible reason for this.... inever faced this problem 
before.....Thanks,Nitin Kapoor2009/12/29 Uttam Sarkar > Can you please check if
