Appendix B Case Study: Troubleshooting Cisco Unified IP Phone Calls

Troubleshooting Intercluster Cisco Unified IP Phone Calls

In the following traces, the user dials the called number (2000) of the Cisco Unified IP Phone, and the process of digit analysis tries to match the number.

16:05:33.484 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="")

16:05:33.484 CCMDigit analysis: potentialMatches=PotentialMatchesExist

16:05:35.921 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="2")

16:05:35.921 CCMDigit analysis:potentialMatches=ExclusivelyOffnetPotentialMatchesExist 16:05:36.437 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="20") 16:05:36.437 CCMDigit analysis:potentialMatches=ExclusivelyOffnetPotentialMatchesExist 16:05:36.656 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="200") 16:05:36.656 CCMDigit analysis:potentialMatches=ExclusivelyOffnetPotentialMatchesExist 16:05:36.812 CCMDigit analysis: match(fqcn="", cn="1001", pss="", dd="2000")

The digit analysis has now completed, and the results appear in the following traces. It is important to note that the following PotentialMatches=NoPotentialMatchesExist reference indicates that the Cisco Unified CallManager cannot match this directory number. Finally, a reorder tone gets sent to the calling party (1001), which is followed by an on-hook message.
