V3 Inbound Routes

What is an Inbound Route?

   Inbound route is a mechanism to handle incoming calls based on the dialed phone number.

You have to create different inbound route for every phone number you have purchased from your VOIP provider such that incoming call to a specific number will be routed to its respective route to execute different functions. When the call enters the route, you can play a Playback sound file, route calls to an IVR, to a queue or perform any available applications.

This section covers topics related to managing inbound routes.

Don't forget to properly configure a Trunk to route incoming calls.

If you use a multi DID trunk, the provider could send the dialed phone number into the SIP header in the "To" field. Take a look at DID Elaboration to properly manage the phone numbers.

The Inbound Routes Section

You can find the Inbound Routes section under the Voice menu:


When you click it, you'll see all configured inbound routes and add new routes:

Create an inbound route

To create an inbound route click the New button  and enter:

 

  • Phone Number: the number on which you receive the calls, usually it's given by your telco provider. 
    It is also called DID.
    Phone Number is not limited to single specific number. It can also be a pattern that represents a series of numbers. A phone number is a pattern if it starts with the underscore symbol (_) and is followed by character(s). The most useful characters are:
    - X which indicates a number from 0 to 9, and
    - . which indicates 0 or more numbers from 0 to 9.
    For example, “_3X” means from 30 to 39 and “12X.” means all numbers starting with 12 plus at least one other number, like 124, 120, but not only 12)

  • Context (e.g. from-sip, from-voip-provider…)

  • Company: associate a route to a Company

  • Alias: (optional) descriptive name associated to the phone number

  • Description (optional)



 

Edit/Modify an inbound route

To edit an inbound route find the route from the list and click on Edit Inbound Route:

In the Settings tab, you can modify Phone Number, Context, Alias or Description.

In the Actions tab, you need to add a one or more applications (see the next paragraph) to execute when the call enters the route. 

 

Applications

To add an application, drag and drop the application from the list of applications and fill out the necessary fields.

Application execution depends on:

  • the position of the application in the actions table. If you add multiple applications for a single inbound route, execution starts from the top application and continues until the bottom. You can drag and drop items in the list to arrange the applications order.

  • the time interval that defines when an application can be executed (by default, it’s set to always).

 

The following table shows the list of applications you can use in Inbound routes:

  • BUSY: Busy signal. The dial command reached its number but the number is busy.

  • NOANSWER: No answer. The dial command reached its number, the number rang for too long, then the dial timed out.

  • CANCEL: Call is cancelled. The dial command reached its number but the caller hung up before the callee picked up.

  • CONGESTION: Congestion. This status is usually a sign that the dialled number is not recognised.

  • CHANUNAVAIL: Channel unavailable. On SIP, peer may not be registered.

(for more details you can explore Channel Variable DIALSTATUS)
