IP-centric speed dial
View Patent ↗The present invention provides speed dial capability for traditional telephones, which are coupled to a terminal adaptor to facilitate calls over a packet network. In operation, the terminal adaptor will receive a speed dial code, such as 12#, from a traditional telephone and use the speed dial code to attempt to initiate a session over the packet network. A proxy will intercept the session request, recognize the speed dial code in the session request, and access an address associated with the speed dial code. The proxy will then use the address corresponding to the speed dial code to initiate a session between the terminal adaptor and another device to facilitate the call. The terminal adaptor will provide the necessary translation between the packet network and the traditional telephony interface to which the traditional telephone is coupled.
