[SIPForum-discussion] Problem with SIP ACK to HOLD REQUEST

[rajesh]

Hi All,
This is my first posting  to sip forum.
I am agree with the nishant view. some times
depending on the proxy configuration , it duplicates
sdp parameters and that is ignored by next node.
so i dont think so it will create any problem.
else
try to remove the duplicates value.

Thanks and Regards
