I have been posting quite a bit lately, so please bare with me, I’m still learning how all of this works! Anyway, I was reading a tutorial on how to dial through a SIP trunk and I saw that the syntax for the Dial application when dialing through a SIP provider is: Dial(SIP/provider/5555555). I see how to use the syntax, however I was wondering if someone could explain to me how it works? By this I mean is it sending the call to the gateway and changing the caller ID to be the “5555555” in this example? If not, how does the gateway know the number you dialed? Please tell me if you need me to try and clarify for you…it is a little hard to explain.
