IntelePeer launches high-strength encryption for SIP trunking service

Infonetics: SIP trunking revenue grew 23 percent in first half of 2012

IntelePeer, a provider of cloud-based unified communications (UC) services, has unveiled high-strength encryption for its SIP trunking service for enterprises. The 4 kilobyte public key encryption is part of Intelepeer's new CoreCloud UC Trunking 3.0 service, which includes high-definition audio.

"While SIP trunking continues to gain traction in the enterprise, there are growing concerns about security. Strong encryption offers one effective approach for addressing these concerns, particularly for protecting SIP trunking routed over public Internet connections," commented Diane Myers, principal analyst with Infonetics Research.

Despite security concerns, SIP trunking revenue grew 23 percent in the first half of 2012 over the second half of 2011, according to the latest figures from Infonetics. Overall, the research firm estimates $377 billion will be spent on VoIP and UC services over the next five years, driven by SIP trunking and hosted VoIP/UC services.

Intelepeer's CoreCloud UC SIP Trunking 3.0 integrates transport layer security (TLS) and secure real-time transport protocol (SRTP) encryption to protect signaling and multimedia content and ensure the privacy and integrity of communications. This reduces the need for enterprises to pay for dedicated data access, such as a T1 circuit or multi-protocol label switching (MPLS) network for their SIP trunking connections, enabling them to securely route communications over their existing corporate data connections, the company explained.

With the addition of TLS and SRTP encryption capabilities, Intelepeer claims its CoreCloud UC SIP Trunking 3.0 service is the only secure SIP trunking offering in the United States that is qualified for Microsoft (Nasdaq: MSFT) Lync.

"The challenge up to now has been that for an over-the-top provider, you really didn't have a scalable way for encrypting and securing information. A lot of enterprises, for a variety of reasons, have required dedicated connections. That limits the flexibility in terms of who you can get a SIP trunk from," said Charles Studt, vice president of product management and marketing at Intelepeer, in an interview with FierceEnterpriseCommunications.

Intelepeer also announced two new CoreCloud UC bundles for SIP trunking services. The two bundles, CoreCloud UC Basic and CoreCloud UC Local, provide businesses with predictable SIP trunking communications costs, the company explained. The bundles are available in a month-to-month package or on a discounted longer-term basis. Customers count up the number of users or ports they want on their communications system and purchase the same number of CoreCloud UC bundles.

"We have added an allocation of toll-free numbers into our bundles. We've added inclusive calling destinations in Canada, and we've added the ability to do high-definition audio calling," Studt explained.

"In terms of trying to enable all of these unified communications features, our value proposition is extending them beyond the firewall over the SIP trunk out to the outside world," Studt concluded.

There is no doubt that SIP trunking is growing in popularity among enterprises. For an in-depth examination of the benefits and challenges of SIP trunking, see our recent special report SIP trunking migration: Enterprise opportunities and challenges.
