Try to dial 711 from Trunk Line TAC number and confirm if this is successful or not.
Success
Ensure You have a entry in dial plan for 711 3 3 as ars, put trace in CM share the trace log. Also check call type should be emergency/public
There is no selection "emergency/public" in my system. However dial plan entry: "711 3 3 ars" worked.
Number min max route pattern type
711 3 3 9 emer
using the command: "change ars analysis 7," I added the line " 711 3 3 1 emer" as we use Route Pattern 1 for local calls.
GOOD JOB!
