Description
The internal 2-port Cisco Ethernet switch allows for a direct connection to a 10/100BASE-T Ethernet
network through an RJ-45 interface with single LAN connectivity for both the phone and a co-located
PC. The system administrator can designate separate VLANs (802.1Q) for the PC and Cisco Unified IP
phones, providing improved security and reliability of voice and data traffic.
A dedicated headset port eliminates the need for a separate amplifier when using a headset. This feature
allows the handset to remain in its cradle, making headset use simpler.
The convenient Volume Control button on the phone provides for easy, decibel-level adjustments for the
speakerphone, handset, headset, and ringer. The handset is hearing aid-compatible (HAC). Additional
volume control gain can be achieved using an inline handset amplifier such as Walker Equipment W-10
and CE-100 amplifiers.
The phone foot-stand is adjustable from flat to 60 degrees to provide optimum display viewing
and comfortable use of all buttons and keys. The foot-stand is keyed to match standard wall-jack
configurations for wall mounting. Two optional wall-mount brackets are also offered, as noted later
in this document.
The Cisco Unified IP Phone 7941G supports Cisco Pre-standard Power over Ethernet (PoE), which
allows powering from any of the Cisco Inline Power-capable blades and boxes. In addition, it supports
IEEE 803.af PoE. The phone can be powered locally with a power supply (part number CP-PWR-CUBE-
3).
More than 24 user-adjustable ring tones are available.
A HAC handset (meets ADA requirements) is available, as well as HAC compliance for magnetic
coupling to approved HAC hearing aids. The dial pad is also ADA-compliant.
The phone offers Skinny Client Control Protocol (SCCP) support.
G.711µ and G.729a audio compression codecs are available.
The phone supports differentiated services code point (DSCP) and 802.1Q/p standards.
The phone supports manufacturing-installed digital certificates, device authentication, and encryption.
Support for more than 20 languages is built in (depends on Cisco Unified CallManager version).
IP address assignment can be statically configured or configured through the DHCP client.
Comfort-noise generation and voice activity detection (VAD) programming are performed on a system
basis.

The phone is interoperable with Cisco Pre-standard PoE and with IEEE 802.3af PoE (the phone is a
Class 2 device); 48 VDC is required; it can be supplied locally at the desktop using an optional AC-to-DC
power supply (part number CP-PWR-CUBE-3=). Use of the power supply also requires one of the
corresponding AC country cords listed in Table 6.
