Assuming all route patterns below are configured on a Cisco UCM, which route pattern will be matched when a user dials 2001?
A. 200[1-4] configured with nonurgent priority
B. 200X configured with urgent priority
C. 200! configured with urgent priority
D. 200[^2-4] configured with urgent priority
E. 20[02-4]1 configured with urgent priority
E is the closes match. You can easily check this
When checked via DNA the following result occurs –
Calling Party Information
Dialed Digits = 2001
Match Result = RouteThisPattern
Matched Pattern Information
Called Party Number = 2001
Time Zone = Etc/GMT
End Device = CMS_RL
Call Classification = OffNet
InterDigit Timeout = NO
Device Override = Disabled
Outside Dial Tone = NO
Call Flow
Route Pattern :Pattern= 200[1-4]
Route List :Route List Name= CMS_RL
Alternate Matches
Partition :Name= test_PT
Pattern
Pattern = 200X
Pattern Type = Enterprise
Call Classification = OffNet
CallManager Device Type = AccessDevice
PatternPrecedenceLevel = PlDefault
PatternRouteClass = RouteClassDefault
Pattern
Pattern = 20[02-4]1
Pattern Type = Enterprise
Call Classification = OffNet
CallManager Device Type = AccessDevice
PatternPrecedenceLevel = PlDefault
PatternRouteClass = RouteClassDefault
This clearly shows that A is the best match
A is correct. Best match.
The correct answer is A :
B is not the best mach…Making a pattern urgent forces the T302 timer to expire as soon as the configured pattern is the best match for the dialed number. This does not mean that the urgent pattern has a higher priority than other
patterns; the closest-match logic still applies.
there are 4 patterns matched by 200[1-4] vs 10 patterns matched by 200X
Very good analysis YM
