The Rise of SIP Trunking

November 2, 2012

Session Initiation Protocol, or SIP, provides enterprises the possibility of reducing telecom operational costs and complexity. SIP trunking also offers the ability to streamline and optimize telecommunications architectures without the need for the replacement of most existing equipment. SIP trunk users can utilize resiliency and back-up strategies, and take advantage of unified communications, even outside the company, to improve collaboration. IT professionals can deploy Session Border Controllers (SBC) with SIP trunking to simplify communications system and policy management, provide a level of security, and to utilize SIP session management, which addresses the challenge of operating in a multi-vendor, multi-protocol telecommunications environment.

Companies, particularly those with global locations, can administer shared resources, greatly reduce long-distance charges, and utilize the same communications protocol layer for all UC elements, instead of separate protocols for each UC application. After two years of flat growth, enterprise use of SIP trunking is on the rise, and organizations that implement them will be empowered by the benefits of SIP via delivery of new services and potentially, reduced operating costs.
