I have a few remote sites that all uses call manager for call control. I have all directory numbers on all phones in all remote sites in a single INTERNAL-PT partition. I would like to configure the system to send all calls out the loca gateway on the each remote site but send voicemail over the WAN.
So, I would not like anyone to be able to call the internal directory number of anyone else except those in there local site. They do not have ta apply AAR as no 5 digit dialling is to be configured. I just want to send all calls over the PSTN except for voicemail.
