Avaya IP Office Phone Issue

[nelliott]

Morning All,

 

We've got a Avaya IP Office v9 phone system and have one extension which is displaying an incompatible message when they try to dial externally, however, internal calls work fine.

 

Any ideas?

 

Thanks in advance!

I'd check in the IPO manager that the user is set to the correct working hours user rights, it may be that they're set to a 'user right' that has external dialing barred?
