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.

Communications management and gateway bypassing system

In one embodiment, an apparatus may include a trunk service unit and at least one logical multimedia terminal adapter (L-MTA). The trunk service unit may be configured to provide session initiation protocol (SIP) service to at least one subscriber equipment in a subscriber network. Each subscriber equipment may have an associated subscriber equipment identifier. The trunk service unit may provide subscriber-facing signaling to communicate with the subscriber network and network-facing signaling to communicate with a stimulus-based network. The L-MTA may be associated with the stimulus based network and may be configured to obtain service from a call management server (CMS) in the stimulus-based network. Each L-MTA may have an associated L-MTA equipment identifier, where the network-facing signaling of the trunk service unit being used to control the at least one L-MTA.

Session initiation protocol communication with endpoints managed by a call management server in a stimulus based network

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.

Multiple voicemail account support for a VoIP system

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.

VoIP call routing

An IP telephone which supports a voice conference call with a plurality of other IP telephones over a packet-switched network is disclosed. The IP telephone exchanges audio and signaling messages with the other IP devices during the conference call, and thereby allows three or more conference call participants to talk together over the packet-switched network. The IP telephone includes a memory, which stores a conferencing module and a channel establishment module, and a mixing module for mixing input signals received at the IP telephone to produce a combined signal output. When played back, the combined signal output to allows the user to hear what was said by the other conference call participants.

System and method for supporting conferencing capabilities over packet-switched networks

An electronic device, such as a telephone, includes a key operable to be pressed into a depressed position, said key being associated with a function, and a control system for initiating the function associated with the key, wherein if the key is pressed into the depressed position and released within a timeout period, the control initiates the function upon release of the key, and if the key is pressed into the depressed position and retained in the depressed position for the timeout period, the control system does not initiate the function upon release of the key.

User interface with key timeout

An IP telephone which supports a voice conference call with a plurality of other IP telephones over a packet-switched network is disclosed. The IP telephone exchanges audio and signaling messages with the other IP devices during the conference call, and thereby allows three or more conference call participants to talk together over the packet-switched network. The IP telephone includes a memory, which stores a conferencing module and a channel establishment module, and a mixing module for mixing input signals received at the IP telephone to produce a combined signal output. When played back, the combined signal output allows the user to hear what was said by the other conference call participants.
