Hi,
We have a 24 channel PRI T1 connected to the PBX. We use DID's. I'm trying to determine the way Caller ID behaves on the incoming calls. Sometimes I can see the number of the caller, and sometimes I see the Name of the DID number from the DID routing screen. I assumed that callers with no ID infromation will appear with the Name of the DID instead, but apparently it happens to callers which display correctly on mobile phone, for example.
What gives?
