Outbound Proxy and Proxy Server for SIP
Posted on 2011-03-03
Hi, what is the difference between an outbound proxy and a proxy server for SIP?
Why are there 2 fields required for connection sometimes?
I'm asking because my voip provider has provided me sip trunking 20 lines. They have said the outbound proxy needs to be a certain proxy, then the proxy server to be another one.
It seems the calls have issues if the outbound proxy is set differently or not set at all. I experienced call drop outs and difficulty in registration.
Can the provider do that?

the outbound proxy is usually one close to you for example on your LAN and it handles all your SIP requests. It can be used for policing and charging purposes.
It is itself a proxy server. Proxy servers in general pass SIP requests on and return responses in a way like SIP routers. HTH.

Both of them are not in the LAN. So I guess the reason why the Outbound Proxy is used in this instance is for policing purposes. I know for a fact that the number of SIP messages to the Outbound Proxy is being controlled and if there's too many, the IP will be blocked for a good ten minutes.
Also, one thing I noticed is that this provider gives back an Unauthorised 404 each time the first invite goes.
Any idea what this is?
