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

device. The TCP handle value for the device remains the same until the device is rebooted or goes offline.

In the following traces, the Cisco IP Phone (1001) has gone off-hook. The trace shows the unique messages, TCP handle, and the calling number, which is displayed on the

Cisco IP Phone. There is no called number at this point, because the user has not tried to dial any digits.

16:05:46.37515:20:18.390 CCMStationInit - InboundStim – OffHookMessageID tcpHandle=0x5138d98

15:20:18.390 CCMStationD - stationOutputDisplayText tcpHandle=0x5138d98, Display=1001

In the following traces, the user is dialing the 3333, one digit at a time. The number 3333 is the destination number of the phone, which is located somewhere on the PSTN network. The digit analysis process of the Cisco CallManager is currently active and is analyzing the digits to discover where the call needs to get routed. A more detailed explanation of the digit analysis was provided in the previous case study.

15:20:18.390 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="")

15:20:19.703 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="3")

15:20:20.078 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="33")

15:20:20.718 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="333")

15:20:21.421 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="3333")

15:20:21.421 CCMDigit analysis: analysis results

In the following traces, the digit analysis has been completed, calling and called party has been matched, and the information has been parsed.

CallingPartyNumber=1001

DialingPattern=3333

DialingRoutePatternRegularExpression=(3333)

PretransformDigitString=3333

PretransformPositionalMatchList=3333

CollectedDigits=3333

PositionalMatchList=3333

In the following traces, the number 0 indicates the originating location, and the number 1 indicates the destination location. The bandwidth of the originating location is determined by BW = –1. The value –1 implies that the bandwidth is infinite. The bandwidth is infinite because the call was originated from a Cisco IP Phone located in a LAN environment. The bandwidth of the destination location is determined by BW = 64. The call destination is to a phone located in a PSTN, and the codec type is used is G.711 (64Kbps).

15:20:21.421 CCMLocations:Orig=0 BW=-1 Dest=1 BW=64 (-1 implies infinite bw available)

The following traces show the calling and called party information. In this example, the calling party name and number is the same because the administrator has not configured a display name, such as “John Smith.”
