SIP Trunking Service

MASERGY has been delivering SIP across our network since 2003, under our inControl Voice solutions.  We have also provided domestic long distance, international long distance, international country-to-country calling and toll-free service. We are now adding originating local VoIP services to our product portfolio.  

MASERGY’s SIP Trunking service is designed for companies deploying an IP PBX. The service is delivered via a standards-based SIP trunk directly to the IP PBX, eliminating the need for additional TDM enterprise gateways, TDM cards and the associated maintenance.

SIP Trunking replaces traditional PRIs or T1s to combine voice and data over a converged network interface. The service includes value-added features such as unlimited inbound calling, unlimited outbound local termination, and enhanced E911 services, while reducing combined data and voice costs by 20 to 40 percent.
