Audio Quality Subjective to the User

Chapter 3 Setting Up the Cisco Unified IP Phone

Understanding the Cisco Unified IP Phone 7960G and 7940G Components

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.

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.

Connecting a Headset

To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the phone. Press the Headset button on the phone to place and answer calls using the headset.

You can use the headset with all of the features on the Cisco Unified IP Phone, including the Volume and Mute buttons. Use these buttons to adjust the ear piece volume and to mute the speech path from the headset microphone.

Disabling a Headset

You can disable the headset through the Cisco Unified Communications Manager Administration application. If you do so, you also will disable the speakerphone.

To disable the headset from Cisco Unified Communications Manager Administration, choose Device > Phone and locate the phone that you want to modify. In the Phone Configuration window for the phone, Product Specific Configuration area, check the Disable Speakerphone and Headset check box.

Using External Devices with Your Cisco Unified IP Phone

The following information applies when you use external devices with the Cisco Unified IP Phone:

Cisco recommends the use of good quality external devices that are shielded (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 or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions:

•Move the external device away from the source of the RF or AF signals.

•Route the external device cables away from the source of the RF or AF signals.

•Use shielded cables for the external device, or use cables with a better shield and connector.

•Shorten the length of the external device cable.

•Apply ferrites or other such devices on the cables for the external device.

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system will perform adequately when suitable devices are attached using good quality cables and connectors.

The phone supports up to six lines, allowing users to manage multiple calls effortlessly. Its user-friendly interface includes programmable feature buttons and a 10/100 Ethernet switch, enabling seamless integration into existing networks.

On the other hand, the Cisco 7940G is a more basic model designed for users who require essential features for their business communications. It includes a monochrome LCD screen and supports a maximum of two lines. Despite its simplicity, the 7940G is equipped with several key features such as integrated speakerphone and mute options, making it ideal for day-to-day communication needs. Both models support Power over Ethernet (PoE), eliminating the need for separate power adapters and ensuring a cleaner, more organized workspace.

In terms of technologies, both the 7960G and 7940G leverage the Session Initiation Protocol (SIP) for signaling and media exchange. They also support secure communication through protocols like Secure Real-time Transport Protocol (SRTP) and Transport Layer Security (TLS). This ensures that businesses can engage in confidential conversations without the risk of interception.

The characteristics that make these models appealing include durability, ease of configuration, and reliability. Organizations can benefit from Cisco’s reliable support and regular updates, ensuring that their communication infrastructure remains robust and secure. With features designed for scalability, both phones can easily integrate into larger systems while maintaining high call quality.

In summary, Cisco’s 7960G and 7940G VoIP phones are exemplary devices that cater to a variety of business communication scenarios. With their blend of functionality, support for essential technologies, and reliable performance, they continue to serve organizations effectively in an increasingly interconnected world. Whether used in a bustling office or as part of a dynamic telecommunications strategy, these models offer excellent value and performance.
