What happens when 3 or more people call into 3CX? I just signed up broadvoice for a single in/out line and was wondering what happens when more then one person calls and I happen to be on the line. Do they get busy signals or can VOIP handle multiple inbound calls? I have service with Ringcentral (which I would like to replace with 3CX) and they can handle multiple people calling the same 800 number without giving a busy. How can I accomplish the same thing with 3CX? Thanks!
