MOBILE DEVICE CALLS VIA PRIVATE BRANCH EXCHANGE

摘要

Communication systems and methods are described that enable mobile devices to route telephone calls via an enterprise telephone system (200). The communication system is configured to receive via a data channel a request from the mobile device (200M). The mobile device (200M) corresponds to a user making a call. The server (250) receiving the request includes a private branch exchange (PBX) and one or more other servers (250) hosted by or coupled to the enterprise (200E). A first call leg is initiated over a first voice channel in response to the request. The first call leg is coupled to the server (250) and mobile device (200M). A second call leg is initiated over a second voice channel, and the second call leg is coupled to the server (250) and a client device (222) corresponding to an intended call recipient. A voice conference call is formed between the mobile device (200M) and client device (222) by joining the first and second call legs.
