Connecting Your Phone

Your system administrator will likely connect your new Cisco Unified IP Phone to the corporate IP telephony network. If that is not the case, refer to the graphic and table below to connect your phone.

Removing the Hookswitch Clip (Required)

Some phones ship with a clip to secure the hookswitch. Before you use your phone, remove the hookswitch clip (if present) from the cradle area. With the clip removed, the hookswitch lifts slightly when you pick up the handset.

Adjusting the Handset Rest (Optional)

Cisco recommends adjusting the handset rest, particularly when wall-mounting the phones, as this will ensure that the receiver will not readily slip out of the cradle. See the table below for instructions.


Set the handset aside and pull the square plastic tab from the handset rest.


Rotate the tab 180 degrees.


Slide the tab back into the handset rest. An extension protrudes from the top of the rotated tab. Return the handset to the handset rest.

Adjusting the Footstand (Optional)

To change the angle of the phone base, adjust the footstand while pressing the footstand button.

Registering with TAPS

After your phone is connected to the network, your system administrator may ask you to auto-register your phone using TAPS (Tool for Auto-Registered Phones Support). TAPS may be used either for a new phone or to replace an existing phone.

To register with TAPS, pick up the handset, enter the TAPS extension provided by your system administrator, and follow the voice prompts. You may need to enter your entire extension, including the area code. After your phone displays a confirmation message, hang up. The phone will restart.

Using a Headset

You can use a wired headset with your Cisco Unified IP Phone. If you use a Cisco Unified IP Phone 7975G, 7965G, or 7945G, you can use a wireless headset in conjunction with the wireless headset remote hookswitch control feature.

Headset Support

Although Cisco Systems performs limited internal testing of third-party headsets for use with the Cisco Unified IP Phones, Cisco does not certify or support products from headset (or handset) vendors.

Cisco recommends the use of good quality external devices, for example, headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of these devices and their proximity to other devices such as mobile phones and two-way radios, some audio noise or echo may still occur. An audible hum or buzz may be heard by either the remote party or by both the remote party and the Cisco Unified IP Phone user. Humming or buzzing sounds can be caused by a range of outside sources: for example, electric lights, electric motors, or large PC monitors. See Using External Devices, page 3, for more information.

Note In some cases, hum may be reduced or eliminated by using a local power cube or power injector.

These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed means that there is not a single headset solution that is optimal for all environments.

Cisco recommends that customers test headsets in their intended environment to determine performance before making a purchasing decision and deploying en masse.

Audio Quality Subjective to the User

Beyond the physical, mechanical and technical performance, the audio portion of a headset must sound good to the user and to the party on the far end. Sound quality is subjective and Cisco cannot guarantee the performance of any headsets However, a variety of headsets from leading headset manufacturers have been reported to perform well with Cisco Unified IP Phones. See manufacturer's sites for details.

For information about wireless headsets that work in conjunction with the wireless headset remote hookswitch control feature, go to the following URL:
