Explanation:
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 device—Choose 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 Profile auth by choices from the drop-down list in SCCP Phone Security Profile or SCCP Device
Security Profile field.
For the entire Unified Communications Manager cluster — Choose 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.
