[reSIProcate] ack callback in dum

[Scott Godin]

According to RFC3261...  SDP body in an ACK is only used if no SDP is in
sent in the original INVITE.  

 

In this case the SDP offer is carried in the 200 and the answer is in the
ACK.  In this scenario the onAnswer callback will be called.

Hi Scott,

Body type application/sdp wherein the ip/port maybe different than the one
sent during INVITE. i am not sure whether the RFC allows it, but knowing
that ACK can contain SDP body, wanted my app to be able to parse this
information and make sure that RTP session is ok. Thanks.

Sachin
