Mitel 470 dial out issue

[bdvtech]

I have a customer that is using a Mitel 470 in their small motel/hotel. There are 2 IP phones and around 30 room phones. The room phones are analog phones with programmable buttons on the bottom. A couple of the buttons are used to call 10 digit phone numbers. Regular calls from the analog phones are made by dialing 9 and the number. Recently, for some strange reason, the room phones are not able to dial out. The IP phones can use 9 and then dial a number but this does not work on the room phones. After 9 is pressed, the user hears a fast busy signal. I installed a backup of the customer's database on my in house test system and I have the same problem. Incidentally, the customer is using analog POTS lines for their phone service. I have been through the programming multiple times, and I cannot figure this out. Hopefully someone can offer some useful assistance. Thank you.

Have you checked the permission sets of the phone?

If the room is stuck in a checked out state you could get this.
