This whiteboard session describes the origination and termination components of inbound calls:


Hey folks, welcome back to another whiteboard session here at AVOXI.

So today we’re going to go over how inbound calling actually works and explain some of the terminology that we use for you to better understand how it works.

Behind me is a quick outline where we have this person in-country making a call from a mobile phone. We have AVOXI services, and we have you as our customer.

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 next method 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. Lastly, 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.

Now the great thing about this is that we can set this up where it’s automatic. 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.

Now, when you buy the service from AVOXI, we request that you commit to the rates for all the different options for a full A – Z coverage. The reason why we do this is for failover and to provide you options on call forwarding preferences.

For example, if your SIP trunk goes down and you phone us or even just log into our online portal, you can make these changes by yourself. What we want to avoid is for you to get a surprise at the end of the month on your bill and asking why you were charged a certain rate. So when you sign up with AVOXI, you agree to the full A – Z rate, so we ensure that your solution works seamlessly.

Thank you.
