The nat_traversal module has a keep-alive mechanism that can be used to keep connections active on proxy servers. Also, using the textops module, new headers can be added an existing headers can be modified.
I haven't read the whole rfc to give you definite answer, but it may be possible to emulate an edge server with a well crafted config.

Dear All,
I wonder if Kamailio supports RFC5626 as edge proxy or outbound proxy.
That is,
Edge Proxy adds a Path header with a flow token
and includes the "ob" parameter when Processing Register Requests.
Eg:
Path: sip:VskztcQ/S8p4WPbOnHbuyh5iJvJIW3ib@ep1.example.com;lr;ob
If does, how can I config it in kamailio.cfg. At present, Kamailio can only forward register msg to sip server and reply 200 OK to SIP UA with “require: outbound” when register accepted. No “Path” and “ob” added in the msg forwarded to SIP server.
You answer is appreciated!!
Sincerely,
Derrick
