A method of setting a path in a network using an Internet protocol to
facilitate voice communications between two devices includes determining
whether a first path having an adequate bandwidth for transferring a
voice over Intent protocol (VoIP) packet between two label switch routers
exists. The method also includes setting a new path having a bandwidth
that is at least two times the necessary bandwidth for transferring a
VoIP packet, when it is determined that the first path does not exist.
