2.3 Add extensions
At the beginning, we need to add some extensions to make internal calls. Each extension acts as
an internal number. There are many types of extensions we can add, we will use SIP, IAX2 and
ZAP extensions in this article.
Before set up the extensions, we need to go to the option page and set the numbers of digit of
each extension. Go to
Option -> Admin Settings
Here we set the number to 4, so each extension will be a four digits number.
Add SIP extensions:
Sip extensions are SIP accounts which allow you to log on the IP04 via SIP terminals such as IP
phone AT-530 or softphone x-lite.
