5235 IP PHONE AND LINE INTERFACE MODULE
The Line Interface module is an optional device that adds an analog phone line (POTS) capability to your 5235 IP phone. If Emergency Call Routing is not programmed on your 3300 ICP, you must use the Line Interface Module to dial emergency calls. For more information on emergency number dialing, refer to Emergency Calls.
If you have a Line Interface Module connected to your 5235 IP Phone, all programming of the Line Interface Module, except the Analog Key, is done by the Installer when your phone is installed. For more information, refer to Program a Hard Key and Using the Line Interface Module.
