Hi all,

 

I'd like to got the same PAI Header in the outgoing 183 like in the corresponding incomming 180.

 

Inc 180:

How can I copy that PAI information? Copy List seems to work just for incomming messages on incomming dial-peers?!

SIP Copy list should work just fine.
1. Create a copylist and mention the header from the incoming message that needs to be picked up i.e. PAI in your case.
2. You apply this copylist to the incoming dial-peer
3. Next you create a SIP profile to grab the copied header stored in a variable which would be "u01". Something like -

voice class sip-profiles <number>
response 183 peer-header sip P-Asserted-Identity copy "<sip:(.*)@" u01

4. Apply this SIP profile to the outgoing dial-peer

You can use the following debugs to see this in action as well-

debug voice ccapi inout
debug ccsip messages
debug ccsip info
debug ccsip feature sip-profile

Unfortunately it did not helped me.

My u2 is always empty.

If I want to copy information of an incoming request to use it on outgoing call leg it works fine.

But if I do like you wrote I see no action before the 183 response is sent.

If I set the sip-profile to the incomming dial-peer there is just an empty u2 variable before 183 is sent.

I also tried to set the copy list to the outgoing dial-peer without success.

Not sure if I am following you.
You need to apply the copy list on the incoming dial-peer and use the peer-header to copy the stored variable from the incoming message to the outgoing message with a sip-profile on the outgoing dial-peer.
Apply the config exactly like I have shown above and send me the "show run" from the CUBE. Also take a log for the debugs that I highlighted with the config in place.
