[SR-Users] Add Record-Route on 200 OK

Hello Daniel,


It seems to work.


I have a side question related to this. If the initial INVITE contains a
Record-Route, for all the subsequent status 1xx, 2xx, etc., the Record-Route
is not kept. Is it normal?

you can use append_hf() inside the onreply_route.

If you have a single IP address, that is easy:

append_hf("Record-Route:  <sip:$Ri:5060;lr> <sip:$Ri:5060;lr>\r\n")

Be careful if you use dialog module with did parameter, or other modules
that need ftag parameter (e.g., uac, acc).

the message to the UA.


Indeed, I'm facing an issue where the 200 OK is relayed to the UA without
Record-Route and with an IP address into the Contact header. So, the UA
sends back his ACK to the Contact instead of the proxy itself. 


Is it possible to achieve this?
