Chapter 3: Telephone System Configuration
There are also several advanced extension options available.The
advanced options establish the connections from the listed extension to
other systems within the Asterisk server. These systems include the
following:
Voicemail - Builds a voice mail box for the extension that can be
reached by dialing the Check Voicemail extension. The Voicemail
extension can be configured. The current default is 6050.
In Directory listing - Asterisk establishes a directory of all extensions
so that inbound callers can reach someone in your office by dialing the
first few digits of the person’s first or last name. The company direc-
tory includes only the name of the extension if this option is checked.
SIP - Identifies whether the extension sends and receives calls using
the VoIP protocol SIP.
IAX - Identifies whether the extension sends and receives calls using
the VoIP protocol IAX.
CTI - Selecting this option (Computer Telephony Integration) allows
the user to connect applications to the Asterisk Management Interface.
Call Waiting - If call waiting is not enabled, the extension accepts
only one call before it is identified as busy.
3-Way Calling - Allows the extension to receive a call and then dial
out to another phone number to conference with the inbound call and
the recipient of the outbound call.
Is Agent - Call queuing is made up of a bank of agents who receive
calls. An extension listed as Is Agent can be added to queues from the
CallQueues option on the left toolbar.
To add new extensions, select New Entry in the area under Extensions and
then click New. The system defaults to four-digit extensions, beginning
with the number 6000.
