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?
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?
