/mcpError Message %UC_CALLMANAGER-4-NotEnoughChans: %[DeviceName=String][AppID=String][ClusterID=String] [NodeID=String]: Not enough channels. Explanation A call attempt was rejected because the requested gateway channel(s) could not be allocated. Some of the more common reasons for the lack of channel to place outgoing calls include: High call traffic volume that has the B-channels in the device fully utilized; B-channels have gone out of service for the following reasons: Taking the channel out of service intentionally to perform maintenance on either the near- or far-end; MGCP gateway returns an error code 501 or 510 for a MGCP command sent from Cisco Unified Communications Manager; MGCP gateway doesn't respond to an MGCP command sent by Unified CM three times; a speed and duplex mismatch exists on the Ethernet port between Unified CM and the MGCP gateway. Recommended Action Add more gateway resources; Check the Cisco CallManager advanced service parameter, Change B-channel Maintenance Status to determine if the B-channel has been taken out of service intentionally; Check the Q.931 trace for PRI SERVICE message to determine whether a PSTN provider has taken the B-channel out of service; Reset the MGCP gateway; Check the speed and duplex settings on the Ethernet port.
