Abstract: An emergency notification system is provided including a switching unit, a plurality of communications devices communicatively in communication with the switching unit, an emergency response unit in communication with the switching unit, a plurality of receiving units in communication with the switching unit. Each of the communications devices is configured to transmit an emergency notification to the switching unit which includes a message and at least one receiving unit address. Further, the switching unit is configured to receive the emergency notification from at least one of the plurality of communication devices and to rebroadcast the emergency notification contained in the message to the emergency response unit and to the receiving unit corresponding to the receiving unit address.

Abstract: An Internet protocol query for Internet protocol private branch exchanges including a private branch exchange that is connected to the public switched telephone network for receiving a call setup request, the private branch exchange not being enabled for receiving calling name delivery information from a telecommunications circuit; at least one of an incumbent local exchange carrier switch and a competitive local exchange carrier switch in communication with the private branch exchange, the at least one of the incumbent local exchange carrier switch and the competitive local exchange carrier switch having the telecommunications circuit not enabled for calling name delivery information retrieval; a network in communication with the private branch exchange; and a calling name delivery database in communication with the network for receiving calling name delivery queries from the private branch exchange based on the call setup request. Methods for routing calls based on ENUM information is also included.

Abstract: A bandwidth negotiation system including a first network, a plurality of end user devices in communication with the network, a multiplexing unit communicatively coupled to the network, a second network, and an analyzing unit in communication with a second network. In addition, one of the plurality of end user devices is configured to send a data message to the multiplexing unit via the first network, and the analyzing unit is configured to receive the data message from the multiplexing unit via the second network and to extract a first identifier and a second identifier from the data message.
