Cisco SIP IP Phones

Cisco Unified CallManager supports the SIP protocol on the following Cisco Unified IP Phone models:

Cisco Unified IP Phone 7970/71

Cisco Unified IP Phone 7960/61

The administrator uses the Cisco Unified CallManager Administration Phone Configuration window to configure an IP phone for SCCP or SIP. If SIP is chosen, additional Cisco Unified CallManager Administration configuration windows get used to configure the SIP protocol; for example, SIP Profile Configuration. See Table 43-6for configuration requirements. For information on SIP Profiles and SIP Dial Rules, see SIP Dial Rules Configuration and SIP Profile Configuration in the Cisco Unified CallManager Administration Guide.

Configuring Phones That are Running SIP With the Same Directory Number

Cisco Unified IP Phones 7906, 7911, 7941, 7961, 7970, and 7971 that are running SIP can support multiple lines with the same directory number in different partitions; however, configuring and using other Cisco Unified IP Phones that are running SIP with multiple lines with the same directory number do not get supported.

H.323 Clients and CTI Ports

Cisco Unified CallManager Administration enables you to configure software-based devices such as H.323 clients and CTI ports. Software-based Cisco Unified CallManager applications such as Cisco SoftPhone, Cisco AutoAttendant, and Cisco IP Interactive Voice Response (IVR) use CTI ports that are virtual devices.
