Chapter 8 Monitoring the Cisco Unified IP Phone Remotely

Network Configuration

Table 8-2 Network Configuration Area Items (continued)

 

 

Item

Description

 

 

 

 

 

 

CallManager 1–5

Host names or IP addresses, in prioritized order, of the

 

 

 

Cisco Unified CallManager servers with which the

 

 

 

phone can register. An item can also show the IP

 

 

 

address of an SRST router that is capable of providing

 

 

 

limited Cisco Unified CallManager functionality, if

 

 

 

such a router is available.

 

 

 

For an available server, an item will show the

 

 

 

Cisco Unified CallManager server IP address and one

 

 

 

of the following states:

 

 

 

• Active—Cisco Unified CallManager server from

 

 

 

which the phone is currently receiving

 

 

 

call-processing services.

 

 

 

• Standby—Cisco Unified CallManager server to

 

 

 

which the phone switches if the current server

 

 

 

becomes unavailable.

 

 

 

• Blank—No current connection to this

 

 

 

Cisco Unified CallManager server.

 

 

 

An option may also include the Survivable Remote

 

 

 

Site Telephony (SRST) designation, which indicates

 

 

 

an SRST router capable of providing

 

 

 

Cisco Unified CallManager functionality with a

 

 

 

limited feature set. This router assumes control of call

 

 

 

processing if all other Cisco Unified CallManager

 

 

 

servers become unreachable. The SRST

 

 

 

Cisco Unified CallManager always appears last in the

 

 

 

list of servers, even if it is active. You configure the

 

 

 

SRST router address in the Device Pool section in

 

 

 

Cisco Unified CallManager.

URL of the help text that appears on the phone.

 

 

 

 

 

 

Directories URL

URL of the server from which the phone obtains

 

 

 

directory information.

 

 

 

 

 

 

Messages URL

URL of the server from which the phone obtains

 

 

 

message services.

7906G, 7911G specifications

The Cisco Systems 7911G is a versatile IP phone designed to enhance communication in enterprise environments. Targeting workers in various organizational settings, this model is known for its reliability, ease of use, and robust features that cater to both basic and advanced telephony requirements.

One of the key features of the Cisco 7911G is its support for Voice over IP (VoIP) technology. Using this technology allows for the transmission of voice signals over the internet rather than through traditional telephone lines. This not only reduces telephony costs but also offers enhanced functionality that integrates seamlessly with existing communication systems.

The phone is equipped with a monochrome graphical display that provides users with clear visibility of their call status, directory information, and menu options. With a resolution of 128x64 pixels, the screen is large enough to offer important information without overwhelming the user. This simplicity makes it an ideal choice for users who require straightforward functionality without the complexity of advanced features.

Ergonomically designed, the Cisco 7911G features a comfortable keypad with dedicated buttons for frequently used functions such as mute, hold, and transfer. It supports multiple lines, providing users with the ability to manage multiple calls simultaneously. Additionally, it offers programmable line keys that can be customized for speed dial or as soft keys for quick access to features.

The device supports Power over Ethernet (PoE), which allows the phone to receive power through the network cable rather than needing a separate power source. This feature not only simplifies installation but also enhances mobility within the workspace, as it reduces cable clutter.

Another significant characteristic of the Cisco 7911G is its compatibility with Cisco Unified Communications Manager, which ensures centralized management of telephony systems. It also supports a range of audio codecs that help in delivering high-quality audio during calls, reducing latency and improving overall communication quality.

Security is also a focus with the Cisco 7911G, as it features a secure access feature that includes Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP) for encrypted voice communications. This ensures that sensitive conversations are protected from eavesdropping.

Overall, the Cisco Systems 7911G is a reliable, feature-rich IP phone that provides an excellent solution for organizations looking to upgrade their communication systems. Its combination of user-friendly design, powerful integrations, and security features makes it a cornerstone in the suite of Cisco telecommunications solutions.
