I have not seen any RFCs which talk about SIP-I(with ISUP encapsulation)
to SIP-I scenario. RFC3398 and ANSI T1.679 covers mostly on ISUP to
SIP-I and SIP-I to ISUP.
 
Does any body know how to handle the following scenario?
 
If you are acting as proxy and you get 183 with SDP and 183 with ACM
separately in 2 different messages, are you supposed to
 
-          Pass it along to as it is, OR
-          Drop 183 with SDP(as it doesn't contain any ISUP
encapsulation) , OR
-          Combine 2 and send 183 with SDP+ACM
 
Really appreciate it if anybody has any solution for this.
 
Thanks,
Amar Bajracharya
