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

The next trace shows that Cisco CallManager is sending out this information to a called party phone (the phone is identified by the tcpHandle number).

16:05:43.578 CCMStationD - stationOutputCallInfo CallingPartyName=1001, CallingParty=1001, CalledPartyName=1000, CalledParty=1000, tcpHandle=0x4fbb150

The next trace indicates that Cisco CallManager is ordering the lamp to blink for incoming call indication on the called party’s Cisco IP Phone.

16:05:43.578 CCMStationD - stationOutputSetLamp stim: 9=Line instance=1 lampMode=LampBlink tcpHandle=0x4fbb150

In the following traces, Cisco CallManager is providing ringer, display notification, and other call-related information to the called party’s Cisco IP Phone. Again, you can see that all messages are directed to the same Cisco IP Phone because the same tcpHandle is used throughout the traces.

16:05:43.578 CCMStationD - stationOutputSetRinger: 2=InsideRing tcpHandle=0x4fbb150 16:05:43.578 CCMStationD - stationOutputDisplayNotify tcpHandle=0x4fbb150 16:05:43.578 CCMStationD - stationOutputDisplayPromptStatus tcpHandle=0x4fbb150 16:05:43.578 CCMStationD - stationOutputSelectSoftKeys tcpHandle=0x4fbb150

Notice that Cisco CallManager is also providing similar information to the calling party’s Cisco IP Phone. Again, the tcpHandle is used to differentiate between Cisco IP Phones.

16:05:43.578 CCMStationD - stationOutputCallInfo CallingPartyName=1001, CallingParty=1001, CalledPartyName=, CalledParty=1000, tcpHandle=0x4fbbc30

16:05:43.578 CCMStationD - stationOutputCallInfo CallingPartyName=1001, CallingParty=1001, CalledPartyName=1000, CalledParty=1000, tcpHandle=0x4fbbc30

In the next trace, Cisco CallManager provides an alerting or ringing tone to the calling party’s Cisco IP Phone, notifying that the connection has been established.

16:05:43.578 CCMStationD - stationOutputStartTone: 36=AlertingTone tcpHandle=0x4fbbc30 16:05:43.578 CCMStationD - stationOutputCallState tcpHandle=0x4fbbc30

16:05:43.578 CCMStationD - stationOutputSelectSoftKeys tcpHandle=0x4fbbc30 16:05:43.578 CCMStationD - stationOutputDisplayPromptStatus tcpHandle=0x4fbbc30

At this point, the called party’s Cisco IP Phone goes off-hook. Therefore, Cisco CallManager stops generating the ringer tone to calling party.

16:05:45.140 CCMStationD - stationOutputStopTone tcpHandle=0x4fbbc30

In the following messages, Cisco CallManager causes the Skinny Station to begin receiving a Unicast RTP stream. To do so, Cisco CallManager provides the IP address of the called party as well as codec information, and packet size in msec (milliseconds). PacketSize is an integer containing the sampling time in milliseconds used to create the RTP packets. NOTE: normally this value is set to 30msec. In this case it is set to 20msec.
