Follow these guidelines when configuring agent phones for Unified CCX agents: ✑ Choose Device > Phone in Unified Communications Manager Administration. The Find and List Phones window is displayed. Enter search criteria to locate a specific phone and click Find. A list of phones that match the search criteria is displayed. Click the device name of the phone to which you want to add a directory number. The Phone Configuration window is displayed. In the Unified Communications Manager Administration Phone Configuration web page, select the required Association Information (on the left) to get to the Directory Number Configuration web page. On this page, make the following changes: - In the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2 (default is 4) for Cisco Unified IP Phones 7900 Series and 3 for Cisco Unified IP Phones 8961, 9951, and 9971. - In the Multiple Call/Call Waiting Settings section, set the Busy Trigger value to 1 (default is 2). - In the Call Forward and Call Pickup Settings section, verify that you do not forward any Unified Communications Manager device to the Unified CCX extension of an agent. - In the Call Forward and Call Pickup Settings section, verify that you do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point. ✑ Always disable (turn off) Secure Real-Time Transport Protocol (SRTP) when configuring a Cisco Unified Communications product. You can disable SRTP for a specified device or for the entire Unified Communications Manager: - For a specified deviceChoose Device > Phone. In the Find and List Phone page, select the required phone device. In the Phone Configuration page for the selected phone, scroll down to the Protocol Specific Information section. To turn off SRTP on the phone device, select any one of the Non Secure SCCP choices from the drop-down list in SCCP Phone Security Profile or SCCP Device Security Profile field. Profile auth by - - For the entire Unified Communications Manager clusterChoose System > Enterprise Parameters. In the Enterprise Parameters Configuration page, scroll down to the Securities Parameters section, to verify that the corresponding value for the Cluster Security Mode field is 0. This parameter indicates the security mode of the cluster. A value of 0 indicates that phones will register in nonsecure mode (no security). ✑ The Unified CCX extension for the agent must be listed within the top 4 extensions on the device profile. Listing the extension from position 5 on will cause Unified CCX to fail to monitor the device, so the agent will not be able to log in. ✑ Do not forward any Unified Communications Manager device to the Unified CCX extension of an agent. ✑ Do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point. ✑ Do not use characters other than the numerals 0 to 9 in the Unified CCX extension of an agent. ✑ Do not configure two lines on an agent phone with the same extension when both lines exist in different partitions. ✑ Do not assign a Unified CCX extension to multiple devices. ✑ Do not configure the same Unified CCX extension in more than one device or device profile. (Configuring a Unified CCX extension in one device or device profile is supported.) ✑ To use Cisco Unified IP Phones 9900 Series, 8900 Series, and 6900 Series as agent devices, the RmCm application user in Unified Communications Manager needs to have "Allow device with connected transfer/conference" option assigned to itself.
