innkeeper PBX™
VOIP/PBX Desktop Digital Hybrid
Telephone Handset
Innkeeper PBX will disable the microphone in the telephone handset when you
press the Broadcast button. Use your telephone to place or screen a call. When
you are ready to take the call on innkeeper PBX, simply press the Broadcast
button. Innkeeper PBX will automatically release the Hold (if Hold is used). Make
sure you do not put the telephone handset back in it’s cradle while you are on a
call. This will still drop the call. Do not disconnect or remove the handset during
your call as this will change the input impedance from the phone line and change
the audio level. If you need to take the call back on your telephone, press the
Handset button on innkeeper PBX. This will disable the inputs and outputs on
innkeeper PBX and connect your handset back to the telephone. Your telephone
will operate as a normal telephone anytime you are in Handset mode. Leaving
the hybrid connected to the handset jack on your telephone will not affect normal
use of your telephone. Audio will only pass through the hybrid when you press
the Broadcast button.
Optional Jumper Settings
There is a jumper located inside the innkeeper PBX at J9 that affects handset
operation. The factory default closed position (jumper covering both pins)
disables only the handset microphone when the Broadcast button is pressed.
Changing the jumper to the open position (either remove the jumper or cover
just one pin) allows you to completely disable both the handset microphone and
speaker when the Broadcast button is pressed.
If the incoming audio level from your telephone is too high and you are
consistently lighting the red –3dB Receive LED, first try decreasing the volume
using the controls on the base of your telephone. If you still cannot drop the
incoming audio level enough, and your unit was purchased after February 2007,
you may need to change jumper J10 inside innkeeper PBX.
There are three possible settings to adjust Caller receive level:
Pins 1 & 2 closed: 0dB (factory default)
Pins 2 & 3 closed: -6dB
Pins 1-3 left open: -12dB
To change the jumper settings, first disconnect power from the innkeeper PBX,
then remove the cover and locate the appropriate jumpers on the printed circuit
board.
