M3904 phones--Wireless headset that does NOT need handset lifter?

M3904 phones--Wireless headset that does NOT need handset lifter?

M3904 phones--Wireless headset that does NOT need handset lifter?

(OP)
I've a customer who is insisting on wireless headsets for their M3904 phones. They want to be able to walk around the workcenter and answer calls directly from the headset.

There are plenty of headsets that can do this, but the sticking point is the need for a handset lifter. For some reason, this customer is absolutely adamant that they do not want to use a handset lifter.

Problem is...electronic hook switch cables are available for many other phones, but apparently not the M3904. It doesn't seem the phone's innards permit anything that doesn't involve lifting the handset.

They don't have any 1100-series IP deskphones, nor licensing for IP users, and budgetary concerns preclude the purchase of either.

I've scoured the interwebs trying to find a solution, but to no avail. Does anyone in these forums know of something that might work?

RE: M3904 phones--Wireless headset that does NOT need handset lifter?

I've found these old reports below that might be related.

MPLR16166 -- TAURUS TELSET: ON HOOK DEFAULT PATH does not work with HFD

M3903/3904 set with CLS HFD. Select 'On hook default path' to 'Headset selected' on the option menu of the set. Press DN key to make or to answer a call, the speech path does't go to headset. The loudspeaker is turned on, and microphone is turned off. The user has to press headset key to use the headset.

####################################

If the Receive pin (Receive in to the headset - Pin 3 on connector ) on a headset connected to an M3904 Taurus telephone set is grounded briefly, it may be interpreted as a 'hookswitch' signal and can clear down an established call. Users may report calls cutting off unexpectedly.

This mechanism is 'Design Intent' - to provide Nortel approved Headsets with the ability to originate or answer calls when a headset is worn.

If the receive pin is grounded under some circumstance, the switching mechanism will be emulated and a hookswitch message will get sent to the call server by the M3904 set.

Please note that this behavior is expected to happen only after the firmware detects the presence of a headset. The 'Onhook - Offhook' indication will lead to a firmware interaction only when the the headset has already been detected.
