Hello,

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>\r\n")

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

Cheers,
Daniel

Hello,

I'm looking for a way to add a Record-Route into a 200 OK before relaying 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?

Regards,

Igor.
