A system for voice-activated dialing using implicit and explicit trunks, said system comprising: a central office in communication with a user telephone; a voice over internet protocol (VoIP) gateway in communication with the central office via an implicit trunk and explicit trunk; a session initiation protocol (SIP) feature server in communication with said VoIP gateway; said central office receiving a call from the user telephone and establishing a first connection; in response to said central office establishing the first connection, said central office initiating a second connection over the implicit trunk between said central office and VoIP gateway; in response to said central office establishing the second connection with said VoIP gateway, said VoIP gateway initiating a third connection with said SIP feature server, said SIP feature server operating a voice-activated dialing platform; in response to the user telephone sending a keyword to said SIP feature server, said central office disconnecting the implicit trunk and connecting the call with said SIP feature server via the explicit trunk; and if said VoIP gateway receives a spoken number, then said SIP feature server receives and translates the spoken number into a computer readable telephone number, and further communicates the telephone number to said VoIP gateway, which, in turn, communicates the telephone number to said central office; and in response to receiving the telephone number from said VoIP gateway, said central office disconnects the explicit trunk and routes the call from the user telephone to the received telephone number via said implicit trunk.
