 Hi Rajesh,

If the UAC is not supporting any of the SDP available in 180, then you will receive "488 Not Acceptable here", and session will be disconnected.

Hi all,
 

  If
SDP in 180 and 200 responses are different, How UAC should behave? According to
RFC 3261 “If the initial offer is in an INVITE, the answer MUST be in a
reliable non-failure message from UAS back to UAC which is correlated to that
INVITE. For this specification, that is only the final 2xx response to that
INVITE. That same exact answer MAY also be placed in any provisional responses sent
prior to the answer. The UAC MUST treat the first session description it
receives as the answer, and MUST ignore any session descriptions in subsequent
responses to the initial INVITE.”  
 

  
 

What I
understood from this one means, if SDP in 180 and 200 are different also, UAC
will take SDP in 180 as answer. Is it like that? What will happen if 180 with
SP is not sending reliably ?
 

  
 

Thanks in
Advance
 

Rajesh
