Summary
A dedicated headset interface isn’t available on the IP111 but it is still possible to connect a headset.
Applies To
This information applies to
- IP111
More Information
Problem Details
The headset is connected to the IP111 handset port. The IP111 can be configured to headset mode, then the headset key can be used a hook switch and the handset equalizer is disabled.
Pinout and signal definition
PIN Assignment of the IP111 handset modular 4P4C connector is :
1 | Mic + |
2 | Receiver |
3 | Receiver |
4 | Mic - |
The microphone is driven symetric with 2.9V 1.35kOhm. Microphone sensivity should be -42db (V/Pa) The Receiver impedance should be 150Ohm typ, 32Ohm min.
Headsets
Since the microphone is connected to a symetric amplifier it is important to use a headset with symetric cabling.
This headsets should work, the marked headset has been tested without problems:
- BIZ-2300 Mono Balanced 2303-825-109
- BIZ-2300 Duo Balanced 2309-825-109 (*)
- BIZ-2400 Mono Balanced 2486-825-109
- BIZ-2300 Duo Balanced 24869-825-109
The cable should be 8800-00-25A, with modular 4P4C connector on one side and headset connector on the other side.
