Hello,
I gave this a try in our office and it worked for me, but it **MAY or MAY NOT** work for you with PRI. I'm not sure if this is going to work in a situation that is using PRI. Unfortunately we only have SIP trunks, so I don't have a way of testing this with PRI, but this **MAY** work for you.
1) Create a System Speed Call that uses the Actual Number of 9 - and I would enable the override toll control option to test.
2) Under the Associated Directory Number form, assign the System Speed Call you created in Step #1 to your analog fax machine port/PLID. Just one fax machine/port to test.
3) Go to that fax machine and replace it with a regular analog phone. Attempt to dial a local number without the leading 9. Make sure to include your local three-digit area code if that is required for a local call.
Does that work for you?
Again, MCD allowed me to program this, but that doesn't mean that it will work with PRI. I would ensure that the feature to provide secondary dial-tone is enabled in your ARS entries. That may help with this test. If this test fails, it's because the full number was not dialed before the call was started (which is required with PRI). I would give it a quick test and try it. If it doesn't work, there is one more feature that we can enable that will probably force it to work, however it may impede your Mitel system if you are using Mobile Extension (discontinued) or Mitel Dynamic Extension/Personal Ring Groups that include external numbers.
Thanks!
