Installing the Cisco Unified Wireless IP Phone 7925G

Connecting Headsets

To connect a headset to the Cisco Unified Wireless IP Phone 7925G, plug it into the headset port on the
right side of the phone.
You can use the headset with all of the features on the Cisco Unified Wireless IP Phone 7925G,
including the Volume and Mute buttons. Use these buttons to adjust the ear piece volume and to mute
the speech path from the headset microphone.

Using Bluetooth Wireless Headsets

The Cisco Unified Wireless IP Phone 7925G supports Bluetooth Class 2 technology with Hands Free
version 1.5 when the headsets support Bluetooth. Bluetooth enables low bandwidth wireless connections
within a range of 10 meters. The best performance is in the 1 to 2 meter range.
There can be a potential interference issues. It is recommended that you:
•
•
Using Bluetooth wireless headsets will likely increase battery power consumption on your phone and
might result in reducing battery life.
For a Bluetooth wireless headset to work, it does not need to be within direct line-of-sight of the phone,
but some barriers, such as walls or doors, and interference from other electronic devices, could affect
the connection.
Pairing Headsets
The Cisco Unified Wireless IP Phone 7925G pairs with headsets using a shared key authentication and
encryption method. The authentication process can require a personal identification number (PIN)
specific to the headset, commonly "0000." The Cisco Unified Wireless IP Phone 7925G can be paired
with more than one headset at a time. Pairing is typically performed once for each headset.
Once a device has been paired, its Bluetooth connection is maintained as long as both devices (phone
and headset) are enabled and within range of each other. The connection re-establishes itself
automatically if either of the devices powers down then powers up. The green-dotted Bluetooth icon
indicates whether or not a device is connected.
When headsets are more than 10 meters away from Cisco Unified Wireless IP Phone 7925G, Bluetooth
drops the connection after a 15 to 20 second timeout. If the paired headset comes back into range of the
Cisco Unified Wireless IP Phone 7925G and the phone is not connected to another Bluetooth headset,
then the in-range Bluetooth headset automatically reconnects. For certain phone types that operate in
power-save modes, the user may have to "wake-up" the headset by tapping on its operational button to
initiate the reconnect.
Note It is recommended that users read the headset user guide for more information about pairing and
connecting the headsets.
