Hi Brett,

Thanks for your reply. However actually the problem i am facing is.

I have call flow as below.

UAC --------------------INVITE
w/SDP---------------------------------------------> UAS
UAC <------------------183 w/SDP along with RSEQ-------------------------
UAS
UAC
------------------------PRACK-------------------------------------------------->
UAS

UAC ----------------------------UPDATE
w/SDP----------------------------------> UAS

Now ideally UAC should wait for 200 OK for PRACK from UAS , but before UAS
reply with 200 OK for PRACK, UAC sends the UPDATE method with/SDP and my
SBC forwarded SIP 500 on leg1 to UAC. So my knowledge says UAC should not
send UPDATE method before getting the 200 OK for PRACK.

Can you please let me know if my understanding is correct on this?

Thanks,
Nitin
