Chapter 1 Product Overview

Cisco IP 7960G/7940G Phone Overview

Cisco IP 7960G/7940G phones are full-featured telephones that can be plugged directly into an MGCP
network and can be used very much like a standard PBX telephone. The Cisco IP 7960G/7940G phone
terminals can attach to the existing data network infrastructure, using 10BASE-T and 100BASE-T
interfaces on an Ethernet switch.

When used with a voice-capable Ethernet switch, one that understands type of service (ToS) bits and can
prioritize VoIP traffic, the phones eliminate the need for a trad it ion al pr opr ieta r y te le ph one se t an d key
system or PBX.

The phone works with a third-party call agent (CA) that u ses Media Gateway Control Protocol (MGCP)
for call control and Basic Telephony eXtensible Markup Language (BTXML) for control of the phone
displays and feature keys. Refer to your CA documentation for descriptions of all other phone features,
displays, and applications that are not described in this guide.

The Cisco IP 7960G/7940G phone also supports an adjustable ring tone, a hearing-aid compatible
handset, and a headset.

See Figure 1-1 and Figure 1-2 to identify the buttons and hardware on your Cisco IP phone.
