I am currently testing 3CX to use in house and potentially resale. My SIP provider (it's a local phone company) says I have to register each number given. In our old phone system this wasn't an issue because I could register them all underneath one number. But in 3CX it appears I have to register each number individually under VOIP Providers. This creates a problem with my Outbound Rules, because I have to set one number as the route and then that line is busy if someone is on it. Am I looking at this completely wrong or what? I have a set of numbers that need to look like they are calling from the main line, and I need the main line to receive calls at the same time. Should each person be using their own DID to call out and I should change the outgoing number ID? Just doesn't seem right.
