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
