IP PHONE AT THE ASTERISK IP PBX
The following configuration illustrates how to create a user with an extension to make and
receive calls using the Asterisk as the PBX. This configuration is defined in the sip.conf file
present along with the other configuration files that are created when Asterisk is installed.
Usually, the configuration files can be found at the /etc/asterisk directory.
;This is used in the "extensions.conf" file to identify this
;physical phone when issuing Dial commands.
[phone1]
;The type to use for the 6867i is "friend".
;"Peer" is used when the Asterisk is contacting a proxy,
;"user" is used for phones that can only make calls
;and "friend" acts as both a peer and a user.
type=friend
;If your host has an entry in your DNS then you just enter the
;machines name in the host= field.
host=dynamic
defaultip=192.168.1.1
;The password that phone1 will use to register with this PBX
secret=1234
dtmfmode=rfc2833;Choices are inband, rfc2833, or info
mailbox=1000
;If a phone is not in a valid context you will not be
;able to use it. In this example' sip' is used. You can use
;whatever you like, but make sure they are the same, you will
;need to make an entry in your extensions.conf file (which we
;will get to later)
context=sip
callerid="Phone 1" <1234>
After this is defined in the "sip.conf" file, some information has to be entered in the
"extensions.conf" file present in the same directory as the "sip.conf" file. The following definition
in the file under the [sip]section/context completes defining the extension for the 6867i phone:
exten -> 1234,1,Dial(SIP/phone1,20)
This definition completes configuring the 6867i phone at the IP PBX system.
