5312/5324 IP Phones User Guide

For Users on Resilient 3300 ICP Systems

If during a call, you hear two beeps repeated every 20 seconds it means that your phone is switching to a secondary 3300 ICP system. The call continues but some of the keys and features on your phone function differently. The keys and most features begin working normally again after you hang up. If your phone switches to the secondary system while your

speaker or handset is muted (that is, while the MUTE light is on), the call remains muted until you hang up. Normal operation resumes when your phone switches back to the primary system. If your phone is idle and switched to the secondary system, you'll see a flashing rectangle on the display. The rectangle remains until the switch to the primary system is complete.

Line Interface Module

The Line Interface Module is an optional device that adds an analog phone line (POTS) capability to your 5324 IP phone only. 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 5324 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 "Using the Line Interface Module" elsewhere in this guide. Note: The 5312 IP Phone does not support the Line Interface Module.
