Stellar Growth of SIP Trunking

By Steven Johnson, President, Ingate Systems, Inc.  |  December 22, 2015

SIP trunking adoption has been on a meteoric rise in 2015. SIP trunking services now generate more than $3.5 billion in annual revenue, according to Frost & Sullivan. IHS (News - Alert) expects enterprise adoption to hit 62 percent by 2017, up from a strong 45 percent today. Carrier-driven SIP trunking deployments will accelerate this growth substantially in 2016 and beyond.

SIP trunking has achieved strong momentum among enterprises and carriers alike. It’s been some time since SIP trunking first hit the scene. After years of successful implementations, people are now confident that SIP trunking is a viable and reliable method of communication. Its flexibility and ease of management provides benefits above and beyond the significant cost savings.

Many of our customers – from smaller businesses to the largest enterprises reaching users around the globe – rely on SIP trunking for their vital communications. These include call centers, businesses that depend on successful connection to customers. The redundancy SIP trunking offers adds another layer of business continuity that’s becoming increasingly crucial.

Carriers are pushing SIP trunking as well. Tier 1 operators and cable companies are continuing to leverage the business-to-business potential with SIP trunking. Rolling out thousands of SIP trunks with one enterprise session border controller generates revenue. It also protects the service provider with security.

Ingate’s SIParator Session Border Controller is designed to resolve the most common problems faced by any business adopting this powerful technology: firewall traversal, interoperability, security, routing, control, diagnostics and much more. With the Ingate range of products, service providers can deliver SIP trunks to any business using any PBX (News - Alert). And with Ingate’s Software SIParator, these issues can be resolved for cloud operators if they install the Ingate SIParator at the enterprise edge. And our SBCs are designed to support small as well as very large businesses where high capacity, internal redundancy, and even 48VDC power are requirements.

SIP trunking is now in the mainstream, and Ingate is proud to have assisted in its widespread adoption. 2015 was a great year for SIP, and the technology has been proven successful. But a significant portion of enterprises has yet to adopt. We look forward to a bright 2016 with continued strong adoption, and Ingate stands ready to assist you in making your installation cost effective and robust.
