Paging via an Analog Extension Port (POT Port)
IP Office analog extension ports are marked as POT. These can be used for the connection of third-party paging equipment.
The IP Office 401 (not available in North America) and IP Office 403 Control Units have integral POT ports.

POT ports can also be installed by the addition of an IP Office Phone Module to the system.

The Paging Amplifier must provide isolation or an additional isolation device should be fitted.
-
The Paging Amplifier (and separate isolation device if used) must conform to the local and national telecommunications device regulation.
-
If not done automatically, it may be necessary to set the Paging Amplifier to give priority to the VOX input.
