[SIPForum-discussion] SIP-I to SIP-I

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
