We have 3905 phones in a dispatch center and just purchased a new radio system from Motorola mc5500. The system came with connection to go to 6 conductor quick connects and then to the headsets for both the phone and radio.
What I am looking for is a technical guide for the m3905 that would tell me how I can connect to the phone to pickup Transmit, Receive, Ground and Off Hook Low.
What we are attempting to get working is the ability to receive and transmit over the radio but when phone rings and we pick up the line we know it’s off the hook and headset would switch over to the phone and Radio would come out external speakers. Also the 6 conductor quick connect for the headset has a button so if you are on the phone you press the button and can still transmit over the radio with it pressed and the person on the phone doesn't here the radio traffic.
Can not find any tech specs on theses phones to get this accomplished.
Any help is greatly appreciated
