/mcpthe load on the PDP by following some or all of these recommendations: 1) consider adding more PDPs and provisioning Unified CM with additional external call control profiles and external call control trigger points in the various configuration pages under the Call Routing menu in Cisco Unified CM Administration; 2) provision a pair of policy servers per external call control profile to enable load balancing; or 3) verify that the PDP server in your deployment meets or exceed the hardware requirements specified in the documentation for Cisco Enterprise Policy Manager (CEPM) or the third- party PDP solution you have deployed. If a 505 response causes the alarm, check to be sure that the PDP supports HTTP version 1.1. Error Message %UC_CALLMANAGER-3-ConnectionFailureToPDP: %[PolicyDecisionPoint=String] [FailedToConnectReason=String][AppID=String][ClusterID=String][NodeID=String]: A connection request from Unified CM to the policy decision point failed. Explanation A connection request to the policy decision point (PDP) failed. Failure may have been due to a network error causing limited or no connectivity between Unified CM and the PDP; because of authentication errors when Unified CM established an HTTPS connection to the PDP; or because the PDP was not in service. Recommended Action Verify that network connectivity exists between Unified CM and the PDP by pinging the policy server host from Cisco Unified OS Administration and take steps to establish connectivity if it has been lost. If the connection failure is due to an authentication problem, verify that the valid certificate of the PDP has been imported to Cisco Unified OS Administration and certificates from every node in the Unified CM cluster have been imported to every node in the PDP. Also, make sure that the PDP service is active. Error Message %UC_CALLMANAGER-6-ConnectionToPDPInService: %[PolicyDecisionPoint=String][AppID=String] [ClusterID=String][NodeID=String]: A connection was successfully established between Unified CM and the policy decision point. Explanation A successful connection from Unified CM to the policy decision point (PDP) has been established Recommended Action Informational purposes only; no action is required Error Message %UC_CALLMANAGER-3-AwaitingResponseFromPDPTimeout: %[PolicyDecisionPoint=String] [AppID=String][ClusterID=String][NodeID=String]: Unified CM timed out waiting for the routing response from the policy decision point. Explanation Unified CM did not receive a call routing response from the policy decision point (PDP) within the time specified by either the Cisco CallManager service parameter, Call Intercept Routing Request Timer, or on the Call Intercept Profile Configuration window in Cisco Unified CM Administration. Recommended Action Check whether the PDP is in service and working normally. Verify that the PDP is not overloaded; if it is, take appropriate action to reduce the load on the PDP by following some or all of these recommendations: 1) consider adding more PDPs and provisioning Unified CM with additional call intercept profiles and call intercept trigger points in the various configuration pages under the Call Routing menu in Cisco Unified CM Administration; 2) provision a pair of policy servers per call-intercept profile to enable load balancing; or 3) verify that the PDP server in your deployment meets or exceed the hardware requirements specified in the documentation for Cisco Enterprise Policy Manager (CEPM) or the third-party PDP solution you have deployed. If necessary, increase the value in the Cisco CallManager service parameter, Call Intercept Routing Request Timer or the value in the Call 5/24/26, 3:34 AM System Error Messages for Cisco Unified Communications Manager 15 - Cisco https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/err_msgs/15_x/ccmalarms15.html 276/343
