My dispatch center has an MIP5000 console with a black Motorola junction box. For now we just use the desk mike but I'd like to use a headset and connect it further to a phone.

I couldn't find any information about this box.



The box itself



How would I go about connecting this console to a phone for headset use.

The pics show the "basic" DDN9492 heasdset box, which gives gooseneck/headset/footswitch capabilities. For telephone interface capability, you would need the "Enhanced" headset box, part# DDN9493, which has an extra "Auxilliary" port where the telephone audio would interface to.

All great info above, but the big question is how does one go about getting an off hook signal from a phone system that doesn't supply one?

Do I need an offhook signal tho?

We just put it through to a 7xxx series Cisco phone's headset jack. I would take the phone off hook with the headset button.

You need to tell the MIP5000 which audio to use, when off hook it needs to route your audio through the headset to the phone. Then when you you press the PTT and/or are back on hook the MIP will send your audio to the radio. Also when off hook it should route the rx audio to speaker vs. the headset.

Depends on what type of phone system you are using. We've used the DEES DSI-375 in a lot of Centrex type systems to provide an off-hook signal:

We have Cisco 7965 on our desk. All that goes into it will be a 4 pin RJ. It does not provide off-hook signal, you take it off hook with a button.

Any ideas?
