Registering with TAPS
After your phone is connected to the network, your system administrator might ask you to
auto-register your phone using TAPS (Tool for Auto-Registered Phones Support). TAPS might 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 might need to enter your entire extension, including
the area code. After your phone displays a confirmation message, hang up. The phone will re-start.
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
In some cases, hum may be reduced or eliminated by using a local power cube or power
Note
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.
