How does inbound calling work?

  • The first thing that happens is the customer calls your number. 
  • We call that the originating leg of the call. 
  • Origination is the inbound portion of the call that goes from the customer who is in-country to AVOXI.
  • Then what we do is get that call from AVOXI to you as the customer.
  •  We refer to that as the terminating leg of the call, which is an outbound call.
  • Now a lot of people ask, “if we’re doing inbound why are we talking about outbound?” From an AVOXI perspective, if I stand here in the middle, I’m receiving the call from the person in country and I’m terminating or making an outbound call to you, the AVOXI customer.
  • There are a number of ways in which we terminate calls to you. 
    • The first method, is a SIP trunk between the two of us. For more information on SIP trunking, you can view the SIP trunking whiteboard session video.
    • The second method, is that can be done is PSTN termination, by PSTN I mean local telephone lines. We can set it up so the call goes to your local lines.
    • The third method,  we can even send this call to another location or your mobile phone. Those are three different ways in which we can terminate these calls to you.
  • We can set this up where it’s automatic, meaning it will failover to route 1,  which is the SIP trunk—the most cost-effective way. 
  • Next, it can send the call to your PSTN line or your local line in your office. And lastly, the call can go to a mobile phone or even a second office if need be.
