Chapter 3 Setting Up the Cisco Unified IP Phone Installing the Cisco Unified IP Phone 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 for the phone, check the Disable Speakerphone and Headset check box. Enabling a Wireless Headset Note The Cisco Unified IP Phone 7971G-GE and 7970G do not support wireless headsets. By default, the Wireless Headset Hookswitch Control option is disabled. You can enable it in the Cisco Unified Communications Manager Administration application. Choose Device > Phone and locate the phone you want to modify. In the Phone Configuration window for the phone, select Enable for Headset Hookswitch Control. On the phone, you can verify that the feature is enabled by choosing Settings > Device Configuration > Media Configuration and verifying that the Wireless Headset Hookswitch Control is set to Enabled. Refer to the wireless headset documentation for information about connecting the headset and using the features. Using External Devices 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. Caution In European Union countries, use only external headsets that are fully compliant with the EMC Directive [89/336/EC]. Installing the Cisco Unified IP Phone You must connect the Cisco Unified IP Phone to the network and to a power source before using it. Table 3-1 describes the tasks. See Figure 3-2 for a graphical representation of the connections for the Cisco Unified IP Phone 7975G, 7971G-GE, and 7970G, and see Figure 3-3 for a graphical representation of the connections for the Cisco Unified IP Phone 7965G and 7945G.
