Phone and Radio Audio in headset at all times

[rastolz]

We have a Centracom Gold Elite system and would like the radio audio to be in the headset at all times instead of changing to the external speaker when a phone is picked up. Does anyone have experience on how to do this? Thanks!

Hmmm, I've never been asked to do this. Normally the phone audio isn't routed to the headset unless it's off hook...which shorts two pins in the back of the CIE. It's easy enough to put a jumper on these two pins to allow the phone audio to be routed to the headset all of the time...but this also is what causes the radio audio to route to the external speaker as well. It should be a fairly straight-forward thing to do, possibly as easy as the cutting of one trace & jumpering it to another. Unless there's multiple circuits being switched...I'd have to check in the CIE maintenance manual to give details. I think the main issue is going to be impedance mis-matches, since they are normally two isolated audio circuits, which will now no longer be the case. I'll try & take a look tomorrow & see what it looks like on paper.

Do you still need the phone Tx audio to mute on at PTT for the radio?

Yes. Thanks
