We have a UC560 with a custom auto attendant. Dial by extension works fine.
Dial by Extension to an extension that has the Call Forward All set to a cell number is not working?
Internal calls to that extension follow the call forwarding.
I've tried changing the call forward all to my own cell number and it also fails.
The message we get is " I'm sorry we are currently experiencing system problems and are unable to process your call."
Is there some default setting that is preventing this for call fraud purposes? Where do I begin? What debug commands would I run?
