Analog Phone cannot dial out

[Frank86]

I have a few analog phones in a hotel connected to a Grandstream GXW4224. They all work fine, except for one that can only dial the front desk but not outside lines. What would be the cause of the problem and the fix?

It may be a dialplan in the ATA, but, check the 3CX Activity Log to see if 3CX receives the dialled number, and is then blocking it due to an extension setting (option), like outside calls being forbidden.

It was an extension setting, thank you. All good.
