Set up overflow only for external calls.
We currently use an answering service to take calls whenever our main reception is unable to answer.
At the moment, we are having the issue where internal calls to reception that don't get answered are then being forwarded to this answering service, which is then charging us for these calls.
Is there any way to setup different overflow handling for internal vs external calls, so that say any internal calls go to voicemail or disconnect when not answered, and external calls can overflow to the answering service?
