Abstract:
1. A method of processing a call comprising: configuring a gatekeeper to forward all dialed phone numbers to a call manager by routing any dialed telephone number starting with 0 through 9 to the call manager, wherein the gatekeeper is incapable of effecting advanced call routing functions including call permission routing, time-of-day routing, and calling or called number translation; receiving a signal at the gatekeeper from a first endpoint requesting an IP address of a second endpoint corresponding to a particular dialed phone number; in response to receiving the signal, transmitting to the first endpoint, by the gatekeeper, an IP address of the call manager rather than the IP address of the second endpoint; transmitting, by the first endpoint, to the call manager, a first setup message including a phone number of the first endpoint and the phone number of the second endpoint; transmitting, by the call manager, to the second endpoint, a second setup message including the phone number of the first endpoint and the phone number of the second endpoint; and transmitting call media between the first and second endpoints without the call media flowing through the call manager.
