Creating custom extensions

A custom extension is related to a certain type of dialing. It lacks of technology and it takes advance on Asterisk's dialplan. Let's imagine that you have a requirement in which a user needs to dial a number throughout the first channel of your E1 trunk, but instead of dialing that number, the user would like to use an easier way to perform special dialing. The CUSTOM Extensions option is very helpful for these kinds of requirements.

How to do it…

Create a custom extension by using the following information: dial: DAHDI/1/11223344555. Therefore, when any user dials extension 7006, the call will be automatically sent to the number 11223344555 by using the first E1 trunk. This is shown in the following screenshot:
