## Abstract

Apparatus and methods are disclosed for client-based control of revising caller identifications (IDs) for communications between a private network and a public network. An apparatus including a telecommunications-providing server and processing circuit that communicates client-specific sets of data over an interface protocol. The telecommunications-providing server revises a caller ID for a VoIP call based on the client-specific sets of data, an identifier that corresponds to a requesting endpoint, and a geographic region determined from the call request. Further, the telecommunications-providing server causes control data to be sent to activate an analog-telephone bridging circuit and redirect the VoIP call by obtaining a dial tone and passes at least a subset of the data packet through the analog-telephone bridging circuit for connecting over the local line. The subset of the data packet includes the revised caller ID which is a local number identified by the determined geographic region.
