3.3 Make free internal calls
Making internal calls are the base requirement for a telephony system. Below are the
settings for this usage. It is base on IP04 but setting is the same in other IPXX products.
System Setup
At the beginning, we need to add some extensions to make internal calls. Each extension acts
as an internal number. There are three types of extensions we can add: SIP, IAX2 and ZAP.
Before set up the extensions, we need to go to the Options --> General Preferences to set
the user extensions range. The default user extensions range is from 6000~6299. The
extension 6000 is used for auto-attendant so don't register on this extension.
Then go to page Dial Plan-->Create New Dialplan to create a default Dial Plan.
