[SIPForum-discussion] How to handle retransmission of SIP packets

[Nikhil Devyalayam]

Hi all
     If any SIP packet got retransmitted because of some reason , do we 
need to respond for every retransmitted packet or just accept one and 
ignore others? Example: If any SIP server got same PUBLISH packet two 
times which is retransmitted,do we need to send back 200 OK for both ,or 
send 200 OK for one and ignore the second.? Please help me on this...

Thanks
Nikhil
