GTT’s SIP Trunking transforms how enterprises do business helping drive productivity and efficiency by integrating diverse communication capabilities onto a single global platform.
Our SIP Trunking offering is interoperable with all major UC platforms and can be seamlessly integrated with legacy equipment. Thanks to GTT’s direct peering with Microsoft, we can deliver dedicated SIP trunks to a client’s Microsoft Teams service. Clients will benefit from the lowest latency connectivity between GTT’s voice network and Microsoft Office 365.
GTT offers a full suite of international services, including DIDs, toll-free, termination and emergency services, providing expansive reach on a global basis. Our global, fully redundant and robust SIP-based network has been specifically designed to meet the demands of bandwidth-intensive communication services.
SIP Trunking is capex-efficient and easily integrated with GTT SD-WAN, MPLS or Internet services thereby eliminating the need for public switched telephone network (PSTN) gateways and ISDN BRIs or PRIs. The service also reduces local and long-distance costs as site-to-site calling is included at no charge. Managing outbound calling is simple, as calls are charged from a single, shared rate card for all sites.
