Hi, My enviroment is like this: phone1---proxy1-----proxy2-----phone2. phone1 register to proxy1, and phone2 register to proxy2, now I initiate call from phone1 to phone2, I noticed that phone1 just resolved proxy2's domain by itself and send invite to proxy2 directly, everything works fine. My question is : How can I force phone1 to send invite to proxy1 and then let proxy1 to route that invite packet to proxy2? Actually, I hope all packet between phone1 and phone2 can go through proxy1 and proxy2, include RTP. This behaviour was determined by phone's configuration or proxy's configuration?

-Signaling can be forced to go through the proxy, but not the media. If you want non-end-to-end media, use a media proxy. -Have a look at SIP trapezoid [1] [2] and decide what you want to go through the proxy (via, R, RR) and what end-to-end -Check your UAs' (i.e. phone) outbound proxy configuration.

My two cents,
