Summary

This Recommendation describes service requirements and architecture for transport of Voice Services over MPLS networks.

Voice Services over MPLS networks include a family of protocols that may be supported over MPLS, including Voice over IP (as specified by IETF), Voice over MPLS (as specified by MPLS Forum) and I.366.2 Voice Trunking Format (based on ITU-T Rec. I.366.2 adapted for MPLS).

Possible approaches for transporting Voice Services over MPLS are provided in Appendix II.

Detailed protocol specifications are subject of other Recommendations.
