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 6757i phone.
This definition completes configuring the 6757i phone at the IP PBX system.
To verify whether the extension has been successfully registered at the IP PBX system, enter the
Asterisk console and reload Asterisk. Use the command "sip show peers" at the console. This will
display the extensions that are registered at the IP PBX system.
This completes the basic set-up for the 6757i phone with 1234 extension at
the Asterisk IP PBX system. Refer to Asterisk documentation for set-up on extended or advanced
features such as voice mail and call forwarding, etc.
