The present disclosure provides a voice signaling transmission method and device. The voice signaling transmission method includes: sending, by a second device, a request signaling to a first device; receiving, by the second device, a signaling for requesting the second device to try a call sent by the first device, and sending a signaling for trying a call to the first device; receiving, by the second device, a ringing signaling sent by the first device and sending a temporary response signaling to the first device; and receiving, by the second device, a signaling for confirming the response and a signaling for confirming the request which are sent by the first device and sending a response signaling to the first device.

A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.

Systems and methods for interconnecting point-to-point (P2P) (i.e. SIP/H323) and web browser compatible video conferencing services. The conference platform gatewaying service may use a virtual web browser participant to send and/or receive video and/or audio over VoIP/Video standards, such as SIP/H323 or other point-to-point protocols into a web browser compatible conference by means of a virtual web browser participant. The conference platform gateway service may create a binding between a SIP address and a web meeting URL. When communication is initiated from a compatible peer device to the gateway/server by means of a point-to-point protocol, the gateway/server establishes a connection to the web-based conference using the binding between URI and URL, and establishes a connection between the Point-to-point and Web browser compatible meeting service.

Methods and systems are described for distributing and receiving fax transmissions via a data connection that is owned by a service provider. In one embodiment, a fax server receives a signaling protocol invite from a telephone service provider in response to the telephone service provider receiving, over a circuit switched network and from a source device, an incoming call signal to a fax telephone number of the service provider. The server responds to the invite by establishing a data connection based on the signaling protocol with the telephone service provider, where the data connection is owned by the service provider. The server receives an incoming fax message that is in a fax format and is routed by the telephone service provider as the source device transmits the incoming fax message. The server transmits the fax message to a destination address.

A system and method for supporting a multi-participant voice conference call using PSTN and Internet networks is described. The method for supporting a multi-participant voice conference call includes receiving voice from a PSTN client. The method also includes receiving voice data from a moderator and from at least one remote client connected to the Internet. The method then proceeds to mix the voice data from the PSTN client with the voice data from the moderator into a first mixed voice data that is transmitted to the remote client that is connected to the Internet. The method also mixes the voice data from the moderator with the voice data from the remote client connected to the Internet into a second mixed voice data that is transmitted to the PSTN client.
