I saw Klaus answered very well on it. Just want to add that RTP is not SIP messages

Subject: [Serusers] Outbound proxy definition

Hi,

I am really frustrated with the definition of outbound proxy:

The outbound proxy is a normal SIP proxy. You configure your client, the phone or software, to use the proxy for all SIP sessions.

I would like to know what is meant by all SIP sessions? Does it include all SIP message as well as voice packets (i.e. RTP packets)?

Could I conclude that outbound proxy = ser + nathelper + rtpproxy/mediaproxy?

Hope someone could answer my questions. Thanks.

Thomas
