Abstract: A method and a system for detecting presence of an application layer gateway (ALG) in a network path between an analog telephone adapter and a communications service provider (CSP), and transmitting a media message by bypassing the (ALG) are provided. A communication management application (CMA) detects, processes, and augments the media message sent by a first user device to a second user device. A message relay server (MRS) processes and manages the media message. The CMA receives the media message from the first user device and detects the presence of the ALG using a message echo server. The CMA scrambles the media message and transmits the scrambled media message to the MRS via a network. The ALG is bypassed due to non-recognition of the scrambled media message. The MRS unscrambles the scrambled media message and transmits the unscrambled media message to the CSP for forwarding to the second user device.

Abstract: A computer implemented method and system for bridging an analog telephone service to multiple network and telephony services (NTSs) provides a multi-service analog telephone adapter (MSATA) with software components and physical communication ports (PCPs). The PCPs establish a communication link to simultaneously access the NTSs implementing communications protocols, and receive user inputs from user devices in a voice mode or a data mode. The software components include a control engine for selectively routing and bridging a call to one or more NTSs based on the user inputs and predetermined criteria, a voice communication engine for accessing a voice communication service, a notification engine for generating and transmitting notifications, and a device management client engine, in communication with a device management server (DMS), for providing remote access to the MSATA for configuring parameters associated with the MSATA and the user devices.

Abstract: A method of managing Voice over Internet Protocol (VoIP) calls with an Internet Protocol Private Branch Exchange (IP PBX) is provided, including: receiving at an IP PBX device an incoming call directed to a target telephone number, said IP PBX device storing a contact list parameter including one or more rule fields, each rule field including a telephone number identifier and an associated target extension identifier; searching the contact list parameter to identify the telephone number identifier corresponding to the target telephone number; and routing the incoming call to one or more target extensions corresponding to the target extension identifier associated with the identified telephone number identifier.

Abstract: In one embodiment, a method includes receiving, at an IP PBX, a SIP INVITE request comprising a Request-URI field identifying a URI of the IP PBX and a header field identifying a target DID number. The method also includes identifying a URI corresponding to the target DID number and forwarding the SIP INVITE request with a Request-URI field identifying the URI corresponding to the target DID number.

Abstract: In one embodiment, a method includes receiving, at an IP private branch exchange (IP PBX), an event notification message from a user agent corresponding to a voicemail system. The event notification message includes a Request-URI field identifying a Uniform Resource Identifier (URI) of the IP PBX and a header field identifying a target mailbox. The method also includes identifying a URI corresponding to the target mailbox and forwarding the event notification message with a Request-URI field identifying the URI corresponding to the target mailbox.
