On one of my systems that dials 10 digits for a local number:
Dialed String 610
Min 10 Max 10
Pattern 1
Type hnpa

Doesn't look any different than yours. Maybe someone with more expertise than I has an answer.

One thing I notice... the telco message of "your call did not go thru" is not quite the same as the one that says "Your call cannot be completed as dialed." which is what I believe it would say if there was a "1" or no "1" issue. You said, "when users are trying to dial a specific number with area code 905..." Is it ONLY that specific number that has the problem? Can users at that location dial the same number from a cell phone? Can users dial other 905 numbers successfully?

Have you tried calling the same number yourself from another system?

Do a list trace tac "###" for the trunk the call is using, have the user dial the number, and see what is being sent out and what error you are getting, if any.

Just some things that I would do narrow down what works and what doesn't.
