According to one embodiment of the invention, a method of processing calls includes configuring a gatekeeper to forward all dialed phone numbers to a call manager. The method also includes 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, the gatekeeper transmits to the first endpoint an IP address of the call manager rather than the IP address of the second endpoint. The call manager is operable to set up a call between the first and second endpoints wherein call media associated with the call does not travel through the call manager.
