The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required t o cor rect t he interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment wit hou t Cisco’s written autho riz atio n may resul t in the equi pme nt no longe r comply ing with FCC re quir ements for Class A or Class B digital devices. In that event, your right to use the equipment m ay be lim ited by FCC regulati ons, and yo u may be r equired to correct any interference to radio or television communicati ons at your own expense.

You can determine whether your equipment is causing int erferen ce by turning it off. If the inter ference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interferenc e stops.

• Move the equipment to one side or the other of the television or radio .

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circ uit from the tel evision or radio. (That is, make certain the equip ment and the television or radio are on circuits controlled by different circui t breakers or fuses.)

Modifications to this product not auth orized by Cisco Sys tems, Inc. could void the FCC approval and negate your auth ority to op erate the prod uct. The Cisco implementation of TCP header compression is an adap tati on o f a pr ogr am d eveloped by the University of California, Berkeley (UCB) as

Preface

Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.0 (SIP), Cisco Unified IP Phones 7905G and 7912G, provides the information you

need to understand, inst all, configure , and mana ge the Cisco U nified IP Phone 7905G and 7912G on you r ne twork. Thi s guide i s int ende d to be use d to administer phones running in a Cisco Unified CallManager Release 5.0 or higher environment.

Audience

Network engineers, syste m administ rators, or teleco m engineer s should review this guide to learn the steps required to properly set up the Cisco Unified IP Phone on the network.

The tasks described are considered to be administration-level tasks and are not intended for end-use rs of t he ph one s. M any of the t asks involve configuring network settings and affect the phone’s ability to function in the network.

Because of the close inte racti on betwee n the Cisco Unified IP Phone and Cisco Unified CallManager, these tasks require familiarity with Cisco Unified C all M anage r.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your ne twork is “down,” or there is a critical impact to your business operations. You and Cisco will commit al l necessar y resour ces aroun d the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of y our business ope rat ion are negatively affected by inadequate performa nce of Cisco pro duc ts. You and Cisco will commit full-time resources during normal business hours to reso lve the situation .

CHAP T ER

An Overview of the Cisco Unified IP Phone

The Cisco Unified IP Phone provides voice communication over an Internet Protocol (IP) network. It functio ns much like a tradi tional ana log telepho ne, allowing yo u to place and re cei ve p hone call s and to access f eatures such a s mute, hold, transfer , a nd speed dia l. In additio n, becau se the ph one is con nected to y our data network, it offers enha nce d IP t el ephony f eature s, inc luding a ccess t o network informati on and c ustom ize able fe atur es .

This manual describes the Cisco Unified IP Phone 7905G and 7912G. The Cisco Unified IP Phone 7905G and 7912G includ e softkeys and an LCD screen. The Cisco Unified IP Phone 7 912G ad ds an int erna l E the rnet swit ch.

These phones encode G.711a, G .711u, G.729a, G.729ab, and decode all variants of G.711 and G.729.
