In a communications network, voice and facsimile calls are established between first and second and second terminals via first and second media gateways in a communications network. Each gateway is capable of autonomous transitioning between a voice over IP (VoIP) call mpde and a facsimile ov er IP (FoIP) call mode. A bearer path for the call is established via a media gateway controller. During call setup, the media gateways exchange confirmation of each gateway's capability to perform autonomous transitioning between VoIP and FoIP call modes. The call is established as a VoIP call, and, on a determination by the media gateways that a facsimile call is required, each media gateway autonomously transitions between its VoIP and FoIP call modes without the intervention of the media gateway controller.
A method of establishing a call between first and second media gateways in a communications packet based network, the method comprising the steps of:
A method of establishing voice over IP (VoIP) calls and facsimile over IP (FoIP) calls between first and second media gateways in a communications network, wherein each media gateway is arranged to autonomously transition between VoIP and FoIP without the intervention of a media gateway controller.
A method of establishing a call between first and second and second terminals via first and second media gateways in a communications network, said gateways each being capable of autonomous transitioning between a voice over IP (VoIP) call mode and a facsimile over IP (FoIP) call mode, the method comprising the steps of:
A method as claimed in 6, wherein each said media gateway transitions from its FoIP call mode to its VoIP call mode after a predetermined period of transmission silence.
A communications network in which voice over IP (VoIP) and fax over IP (FoIP) calls can be established between media gateways via an Internet Protocol (IP) network, wherein each media gateway is arranged to autonomously transition, subsequent to call establishment, between VoIP and FoIP without the intervention of a media gateway controller.
A media gateway for establishing voice and facsimile calls over an Internet Protocol (IP) network, the gateway being arranged to autonomously transition between a VoIP call mode and a FoIP call mode without the intervention of a media gateway controller.
A media gateway as claimed in cliaim 13, and arranged to transition from its FoIP call mode to its FoIP call mode after a predetermined period of transmission silence.
