Hi Salil,
The scenario would be like :
1. Initial INVITE is without SDP
2. 180 Ringing containing SDP Offer
3. Now Initiating party will send PRACK for 180 ringing with answer to
offer
Thanks and Regards,
Vivek Talwar

HI Experts ,
Do PRACK Msg contain SDP information . as per Standard theory PRACK is
only acknowledgement.
But in my case I can see that Prack is coming with SDP .
Kindly suggest what can be the reason.
Thanks,
Best Regards
