Abstract
A private branch exchange (PBX) server determines a caller identification (ID) of a voice call received from a first phone system attempting to reach a second phone system. The PBX server transmits a request to a remote phone number resolving server for categorizing the caller ID. In response to a response received from the remote phone number resolving server indicating one or more categories associated with the caller ID, the PBX server processes the voice call based on the one or more categories.
