[cisco-voip] Interdigit timeout issue for 7 digit calls

[Kevin Thorngren]

Hi Erick,

In the CCM trace look for the Digit Analysis Results, for example:

09/15/2005 16:37:19.435 CCM|Digit analysis: analysis  
results|<CLID::StandAloneCluster><NID::10.10.10.3><CT:: 
1,100,119,1.499977><IP::10.10.21.7><DEV::SEP00115CBAD09E>
09/15/2005 16:37:19.435 CCM||PretransformCallingPartyNumber=9193
|CallingPartyNumber=9193
|DialingPartition=par-internal
|DialingPattern=9190
|DialingRoutePatternRegularExpression=(9190)
|DialingWhere=
|PatternType=Enterprise
|PotentialMatches=NoPotentialMatchesExist

If it has PotentialMatches=NoPotentialMatchesExist then CCM does not  
have any other patterns it can match.  If it has something else, such  
as PotentialMatches=PotentialMatchesExist or  
PotentialMatches=ExclusivelyOffnetPotentialMatchesExist, then this  
means CCM has matched a pattern but can match other patterns if more  
digits are dialed.

The easiest way I have found to find overlapping patterns is to go to  
Route Plan > Route Plan Report.  Click on the "View in File" link on  
the right side.  Then view the CSV file in Excel.  This provides a view  
of the configured route plan in SQL.  If this doesn't help then you  
will need to look at the dialing forest on the node that the phone is  
registered to.  Follow these steps to dump the dialing forest:

- Enable the "Dialing Forest Dump Enabled" CallManager Service parameter
- Dial **##*4 on the IP Phone that is placing the test call - you will  
hear reorder
- Search for "dialing forest" in the latest CCM trace on the node the  
phone is registered to

Dumping the dialing forest can be CPU intensive in a large network.  I  
have not had issues with this in smaller networks but do be careful.
