Using an EHS36 with an EXP39 and T28P - Rayfield - 02-20-2014 01:01 AM
I'm trying to use an EHS36 with a T28P and EXP39.
The T28P has firmware version 2.71.0.168 in it. We're using a 3CX IP PBX.
I tried updating the firmware in the EHS36 and the EXP39, but the instructions for setting this up are kind of old (back when 2.60.200.242 was current T28P firmware). So, I'm not sure that the firmware was actually updated in the EHS36 and the EXP39.
The physical setup that I'm using is:
The EXP39 "IN" connects to the T28P "EXT" jack with a short cable.
The EHS36 connects to the "OUT" jack on the EXP39 with a short cable.
Any suggestions on how to get this to work correctly?

Hi JRayfield,
Please notice that the upgrading version for EHS36 and EXP38/39 is different.
Please refer to the documentation in corresponding module.

Ok. So now I understand. I need to put these 'special' versions of firmware in my T28P phone, and then this will allow me to do the updates to the EHS36 and EXP39.
Once the EHS36 and EXP39 are updated, can I then put the latest firmware back into the T28P (the latest that has been tested with 3CX) and will the T28P still work correctly with both the EHS36 and the EXP39 connected?

Yes. You should upgrde to the latest 3CX version that can work well for you. Those special versions just for upgrading EXTs.
