Cisco IP Telephony Troubleshooting Guide for Cisco CallManager Release 3.0(1)

routing the call to a Cisco IP Phone located in Cluster 1, then the following messages would help you find the cause of the problem.

16:02:51.671 CCMRouteGroup - DeviceName=’’172.16.70.245’’

16:02:51.671 CCMRouteGroup -AllPorts

Part of the initialization process shows that Cisco CallManager is adding “Dns” (Directory Numbers). By reviewing these messages, you can determine whether the Cisco CallManager has read the directory number from the database.

16:02:51.671 CCMNodeId: 1, EventId: 1540 EventClass: 2 EventInfo: Call control started

16:02:51.843 CCMProcessDb - Dn = 2XXX, Line = 0, Display = , RouteThisPattern, NetworkLocation = OffNet, DigitDiscardingInstruction = 1, WhereClause =

16:02:51.859 CCMDigit analysis: Add local pattern 2XXX , PID: 1,80,1 16:02:51.859 CCMForwardManager - Started

16:02:51.984 CCMCallParkManager - Started 16:02:52.046 CCMConferenceManager - Started

In the following traces the Device Manager in Cisco CallManager is statically initializing two devices. The device with IP address 172.17.70.226 is a Gatekeeper and the device with IP address 172.17.70.245 is another Cisco CallManager in a different cluster. That

Cisco CallManager is registered as an H.323 Gateway with this Cisco CallManager.

16:02:52.250 CCMDeviceManager: Statically Initializing Device; DeviceName=172.16.70.226

16:02:52.250 CCMDeviceManager: Statically Initializing Device; DeviceName=172.16.70.245

Cisco CallManager Registration Process

Another important part of the SDI trace is the registration process. When a device is powered up, it gets information via DHCP, connects to the TFTP server for its .cnf file, and then connects to the Cisco CallManager specified in the .cnf file. The device could be an MGCP Gateway, a Skinny Gateway, or a Cisco IP Phone. Therefore, it is important to be able to discover whether or not devices have successfully registered on the Cisco AVVID network.

In the following trace, Cisco CallManager has received new connections for registration. The registering devices are “MTP_nsa-cm1” (MTP services on CCM1), and “CFB_nsa-cm1” (Conference Bridge service on CCM1). These are software services running on

Cisco CallManager but are treated internally as different external services and are therefore assigned a TCPHandle, socket number, and port number as well as a device name.

16:02:52.750 CCMStationInit - New connection accepted. DeviceName=, TCPHandle=0x4fbaa00, Socket=0x594, IPAddr=172.16.70.228, Port=3279, StationD=[0,0,0]

16:02:52.750 CCMStationInit - New connection accepted. DeviceName=, TCPHandle=0x4fe05e8, Socket=0x59c, IPAddr=172.16.70.228, Port=3280, StationD=[0,0,0]

16:02:52.781 CCMStationInit - Processing StationReg. regCount: 1 DeviceName=MTP_nsa-cm1, TCPHandle=0x4fbaa00, Socket=0x594, IPAddr=172.16.70.228, Port=3279, StationD=[1,45,2] 16:02:52.781 CCMStationInit - Processing StationReg. regCount: 1 DeviceName=CFB_nsa-cm1, TCPHandle=0x4fe05e8, Socket=0x59c, IPAddr=172.16.70.228, Port=3280, StationD=[1,96,2]
