Hi Rohit,
As per your description, I understand that PAI header is received in
multiple lines. Please refer RFC-3261, section 7.3.1 Header Field Format
to check whether your header format is correct. Hope you will get the fix.
Thanks,
Alok

Hi Andrea,
UAS should simply ignore the malformed ACK messages. Since the ACK message
is malformed, UAS will re-transmit the 400 response of INVITE for 32
seconds.

Hi Frank,
Refer RFC-3326 for detailed information about Reason header.

Hi Vivek,
Here the issue is media is not in sync. If UAS is not providing the SDP in
answer, how UAC can ensure whether the ongoing media is reliable anymore
and if the session is not reliable, it should not be continued.

Hi Tarun,
IMO, this behavior is correct as it violates the offer-answer model. The
answer must have overlapped SDP. But in mentioned scenario, the media at
UAC and UAS is not in sync and therefore UAC should terminate the dialog in
such scenario.
Thanks,

ays the same or increases. Deleted media
streams from a previous SDP MUST NOT be removed in a new SDP;
however, attributes for these streams need not be present"
