Running CUCM 188.8.131.520-3
Some handsets when making international calls get an error *AA*NOT SUITABLE FOR DATA#
The call still connects but that message is displayed on the screen of the phone.
I know that the error is from the PRI/BRI (it's an isdn message from the provider)
Just wondering if there is a way to supress these messages on the gateway or if it needs to be blocked by the provider.
Thanks in advance
