;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 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.
