One Connection to Global Communication
GTT’s SIP Trunking offering goes beyond voice transport, transforming how enterprises do business. From voice to video to instant messaging, we help you drive productivity and efficiency organization-wide, through seamless integration of diverse communication capabilities.
Flexible and Secure
Our SIP Trunking offering is interoperable with all major UC platforms, including Skype for Business, Avaya, Cisco, Siemens and ShoreTel, and can be seamlessly integrated with legacy equipment. We also provide a secure SIP Trunking service option that guarantees encryption of sensitive call signaling and media with TLS and SRTP.
Comprehensive Global Footprint
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.
Drives Cost Savings
SIP Trunking is capex-efficient, 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. Furthermore, SIP Trunking provides bundled options to include per-minute usage in the monthly service charge.
Meets Business Continuity Objectives
GTT’s SIP Trunking offering has built-in redundancy at the trunk level. Each customer is connected to dual GTT PoPs with redundant switching capability at each location. For enterprises seeking additional resiliency, we also offer a secondary failover option to an additional PoP or failover at the individual telephone number level, with routing based on time of day, site availability, traffic flow and more.
