Abstract:
1. A method for routing direct-dialed voice-band calls over an internet protocol network, comprising: receiving a direct-dialed voice-band call from a calling party telephone number associated with a telephone attached to a circuit-switched public switched telephone network, the direct-dialed voice-band call being associated with a destination number, wherein the calling party telephone number is associated with a telephone bill; determining if the destination number is served by an internet protocol gateway by searching an internet protocol command center database in communication with an internet protocol gateway serving the calling party telephone number; routing the direct-dialed voice-band call to the destination number that is served by the internet protocol gateway as a voice-over-Internet protocol telephone call, via a direct link from a local access provider network to an internet protocol gateway that bypasses the public switched telephone network located between the local access provider network and the internet protocol gateway, if the calling party telephone number is registered for a voice-over-internet protocol service and if the destination number of the direct-dialed telephone call is accessible by the voice-over-internet protocol service; generating a voice-over-internet protocol billing record for a voice-over-internet protocol portion of the direct-dialed voice-band call via a switch in the public switched telephone network; and adding the voice-over-internet protocol billing record to the telephone bill.
