Estimating the term…
Providing fail_over call processing services by sniffing signaling traffic, without the overhead of configuring/provisioning terminals (phones), call servers etc. According to an aspect of the present invention, the integrated device operates as a backup call server when external call servers are unavailable. In one embodiment, the integrated device checks whether a first call server, to which a call setup request is destined to, is available, and forwards the request to another call server if the first call server is unavailable. According to another aspect, the integrated device detects the access information of each terminal registering with a call server, and uses the detected information to provide responses to call setup requests when the call servers are unavailable. As a result, the IP phones in a local network can continue initiating calls even when call servers located at remote sites, become unavailable.
A method of supporting Voice Over Internet Protocol (VoIP) calls on a first network, said method being performed in a device, said method comprising:
A method of supporting Voice Over Internet Protocol (VoIP) calls in a router connecting a first network to a second network, wherein said second network comprises a first call server, said method comprising:
A computer readable medium carrying one or more sequences of instructions for enabling a device to facilitate VoIP calls to be initiated on a first network, wherein execution of said one or more sequences of instructions by one or more processors contained in said device causes said one or more processors to perform the actions of:
A computer readable medium carrying one or more sequences of instructions for causing a router to facilitate VoIP calls to be initiated on a first network, wherein said router connects a first network to a second network, wherein said second network comprises a first call server, wherein execution of said one or more sequences of instructions by one or more processors contained in said device causes said one or more processors to perform the actions of:
An integrated device containing a plurality of interfaces, each of said plurality of interfaces connecting to a corresponding one of a plurality of paths, said integrated device comprising:
An integrated device for supporting Voice Over Internet Protocol (VoIP) calls, said integrated device connecting a first network to a second network, wherein a first call server is located in said second network, said device comprising:
