Hi Shahid,
Just a note, TAC does not support Dialing from Outlook officially as it has never been tested.....
To CallManager a + is a wildcard in the route pattern:
Route pattern wildcards and special characters allow a single route pattern to match a range of
numbers (addresses). Use these wildcards and special characters also to build instructions that
enable the Cisco CallManager to manipulate a number before sending it to an adjacent system.
Wildcards and special characters supported by Cisco CallManager.
+ The plus sign (+) wildcard matches one or more occurrences of the preceding digit or wildcard
value.
The route pattern 91X+ routes or blocks all numbers in the range 910 through
91999999999999999999999.
Valid entries for a transformation pattern are
Calling Party Transform Mask 0 1 2 3 4 5 6 7 8 9 X * #
