MTS Allstream launched an MPLS-based IP Trunking service that enables enterprises to seamlessly interconnect their PBXs to the PSTN. IP Trunking uses a quality-of-service enabled IP connection between the PBX and MTS Allstream’s MPLS network, replacing ISDN PRI (Primary Rate Interface) facilities. The service supports both SIP and H.323 protocols.
MTS Allstream is delivering the IP Trunking Service through its national IP/MPLS network, which leverages Cisco System’s CRS-1 Carrier Routing System platform.
