[asterisk-users] Using Asterisk to route call via an outbound proxy
Hello, I want to use Asterisk to use Kamailio as an outbound proxy for routing calls to remote SIP end points, one option could be to use a default peer, but in my case, my outbound proxy can change based on the remote end point, so this option doesn't work. And another problem is that I don't know how to configure Asterisk to prepare the Request-URI based on the remote end point and not based on the outbound proxy address? What is the best way to do it?

Speaking from chan_pjsip it does not have a mechanism to set the outbound proxy on a per-call basis, it's strictly controlled by the endpoint. You'd need multiple or construct endpoints dynamically (for example using the ARI push configuration). As for not rewriting the request URI you need to use loose routing by specifying ;lr in the outbound proxy URI. Example: sip:example.com;lr If used in a configuration file: sip:example.com\;lr The '\' is so the configuration parser does not treat it as a comment.

[asterisk-users] Using Asterisk to route call via an outbound proxy
I'm using chan_sip, I experimented with adding a 'Route' header in the originate command and used the Dial command like 'SIP/peer/exten', but problem is that Request-URI isn't populated correctly. I'm using Asterisk 13.
