I am trying to set up paging between 2 cisco 8961 phones. I have added 2 ext for each phone. one for main outbound calls and 1 for paging. The one for paging, I have set internal Auto answer = Intercom.
The phones ring when you try but the auto answer never picks up it just rings and rings. I output for asterisk is
