Telephone System Replacement With Paging System



Telephone System Relocation
in August 2017

Relocation of a customer’s NEC DSX-40 Telephone System. Programmed to ring on all phones, if no one answered, or they missed the call that was the end of it. It was originally installed and left with the default settings. I found out what their needs were and reprogrammed the system (with their permission ) in a way that fit their needs. I programmed the phone systems built in Auto Attendant to pick up after the 5th ring and let the caller enter an extension number or zero for the receptionist. If the extension did not pick up I had it automatically go to the analog port where I had a PC ( actually one they had laying around because it was old and obsolete But not for this) with a inexpensive voice mail program email the voicemail message to the person it was intended for. I used the same pc for the music on hold. Sounds expensive but it only took about 2 and a half hours from first change to last test.

Music On Hold

My customer didn't know that the NEC DSX has a built in Music On Hold or you can plug in a old phone or IPod for a music player.

External Paging

With the external Page Port I was able to get the overhead paging to work. Unfortunately they didn't have a horn in the warehouse, just Powered Ceiling Speakers. We ordered a Volcom horn kit from Teledynamics for about $80 it comes with a power supply. Ill come back and install it next week and that will be the end of the NEC installation
