Chapter 1 Product Overview
Cisco SIP IP Phone Connections
Note
Only the network port (labeled 10/100 SW) supports inline power
from the Cisco Catalyst switches.
For redundancy, you can use the Cisco AC adapter even if you are using inline
power from the Cisco Catalyst switches. The Cisco SIP IP phone can share the
power load being used from the inline power and external power source. If either
the inline power or the external power goes down, the phone can switch entirely
to the other power source.
To use this redundancy feature you must set the inline power mode to auto on the
Cisco Catalyst switch. Next, connect the un-powered Cisco SIP IP phone to the
network. After the phone powers up, connect the external power supply to the
phone.
Using a Headset
The Cisco SIP IP phone supports a four or six-wire headset jack. Specifically, the
Cisco SIP IP phone supports the following Plantronics headset models:
•
Tristar Monaural
•
Encore Monaural H91
•
Encore Binaural H101
The Volume and Mute controls will also adjust volume to the earpiece and mute
the speech path of the headset. The headset activation key is located on the front
of the Cisco SIP IP phone.
Note
When using a headset, an amplifier is not required. However, a coil
cord is required to connect the headset to the headset port on the
back of your Cisco IP Phone 7960. For information on ordering
compatible headsets and coil cords for the Cisco IP phone 7960, see
