i an trying to have a dial pattern match an exact number the number is 1555-555-0911 this is an e911 test number for voip.ms
i want to add that exact number into the dial pattern for the emergency call outbound route so it can be monitored incase someone decides to play with emergency services
I believe that FreePBX adds the _ to cause Asterisk to use pattern matching. As such the -'s will be ignored, in both the number and the pattern. Apart from that detail, matching an exact number can be done the obvious way.
What have you tried and what has gone wrong.
(1555-555-0911 as a FreePBX outbound pattern, will match 1555-555-0911, but it will also match 15555550911, and 15555550911, as a FreePBX outbound pattern, will match 1555-555-0911. The actual Asterisk pattern used has an initial underscore, and without that will match character for character.)
