The I.366.2 Voice Trunking Format is designed to provide a uniform way to carry voice calls over MPLS. The format also creates a bridge between old and new phone networks, according to Gary Leonard, MPLS/Frame Relay Alliance's vice president of marketing.

Although the alliance's standard is not binding, Leonard expects it will have a major impact on the technology choices of its members, which include Verizon Communications, the largest U.S. phone company, gear maker Cisco Systems and long-distance providers AT&T and MCI.
