Pbx dialing start after 4 digits unless 1st number is a 5 or a 6

I upgraded a system from 2.7 to 2.8 so I could use the dial by name directory.

It is on Asterisk with dahdi 2.4.0. The sys tem was fine under 2.7 and I didn’t have any special dial patterns or route permissions.

Now after I dial anything that doesn’t start with a 5 or a 6 it connects and starts calling before I can plug in the 5th digit and the rest of the 7 digit number.

Do I need to change anything in my setup after an upgrade to 2.8. I know it handles dial patterns differently.


It only happens on Aastra phones. I do not have auto-provisioning.

Some of the phones picked up a bad dial plan from an old system that was still on line and auto-provisioning the new phones that were manually set.
