Connecting Microphones to a Two-Phone Setup
You can attach up to two analog extension microphones or one Polycom HDX
Microphone Array to a two-phone setup.
You can connect an analog extension microphone to just one of the phones, or
connect an analog extension microphone to each phone. You can connect a
Polycom HDX Microphone Array to one phone only (you cannot connect a
Polycom HDX Microphone Array to each phone).
To connect microphones to a two-phone setup:
>>
Connect the free end of a microphone cable to the available microphone
connector on one of the phones. It does not matter which phone you attach
the microphone to.
If you want to attach two analog extension microphones, connect the other
analog extension microphone to the microphone connector on the other
phone.
The following figure shows a two-phone setup with two analog extension
microphones (the maximum number you can attach for this setup).
