How to get on-hold working on a
Panasonic KXT Telephone System
Panasonic systems are probably the easiest traditional telephone systems to install on hold messaging onto.
You will need an MoH player
This will broadcast an on-hold production into your telephone system in a constant audio stream.
All Panasonic PBX systems have a 3.5mm jack input labeled MoH (Music on Hold)
There is no programming required, all you will have to do is to adjust the volume on the player to the correct level.
