Twilio Introduces Public Beta of New Elastic SIP Trunking Service

New Offering Uses Highly Resilient Global Cloud Architecture to Bring On-Demand Provisioning, Global Scale and a Richer Feature Set to the World of SIP Trunking

SAN FRANCISCO, CA--(Marketwired - Nov 17, 2014) - Twilio, the cloud-based communications company, today announced the availability of Twilio Elastic SIP Trunking, an entirely new approach to SIP Trunking that uses the power of the cloud to bring instant provisioning, global reach and data-driven routing to the world of SIP Trunking. Cloud Communications ISVs and geographically distributed enterprises can use Twilio Elastic SIP Trunking to scale their global PSTN connectivity on demand, with no long-term contracts or complex carrier negotiations. Twilio Elastic SIP Trunking offers termination to nearly every country, local phone numbers in 50 countries, on-demand provisioning and elastic scaling, all delivered by a highly resilient cloud architecture.

Lifesize, a division of Logitech and a leading provider of video conferencing around the world, has adopted Twilio for SIP Trunking. "Lifesize Cloud delivers cloud video conferencing that's as easy, as lifelike and as remarkable as meeting in person," said Michael Helmbrecht, VP of product marketing for Lifesize. "We partnered with Twilio for SIP Trunking because it is like getting voice connectivity from every carrier in the world with a pay-as-you-go pricing model. Plus, as we expand Lifesize Cloud services globally, we're seeing a much faster time-to-market for adding voice capabilities in new countries because we no longer have to do any capacity planning, negotiate separate contracts or test individual connections."

Traditional SIP Trunking offerings typically require custom quotes and manual provisioning, which once configured provide only basic voice connectivity. Twilio SIP Trunking by contrast allows you to instantly provision your IP infrastructure with global voice connectivity so one connection to Twilio can replace hundreds of country-specific carriers. With trunks connected to points of presence in five continents, phone numbers in nearly 50 countries and termination to virtually every country in the world, Twilio Elastic SIP Trunking enables rapid global deployment and a significantly richer feature set including:

  • Numbers on a SIP Trunk that can send and receive SMS and MMS (in some markets).
  • Data-Driven Routing that leverages real-time quality measurements to dynamically route outbound calls to the best carrier, providing yet another point of resiliency and quality that other offerings cannot provide.
  • One-click call recording at the SIP layer, with no additional hardware or per-user fees -- just a simple per-minute charge for cloud storage of the recording.
  • Failover to powerful TwiML scripting to specify what failover logic should apply to replicate on-premise IP-PBX functions if a local internet outage occurs.
  • Multi-tenanted SIP Trunks with per-tenant billing records and logs, making it easy to track usage by department, account or use case all under one master account.

In addition, Twilio provides unlimited usage with fees as low as $0.004 per minute.

"The traditional SIP Trunking product and buying experience is outdated," said Jeff Lawson, CEO and co-founder of Twilio. "Twilio believes by providing access to the reliable global carrier connectivity that Twilio has long used for other services, customers will finally have access to a modern SIP Trunking service that lets them innovate far faster than they've been able to with old-world SIP Trunking offerings. We can't wait to see what customers build when the walls that hamper innovation continue to crumble."

Twilio SIP is being launched in public beta in order to gain broader customer feedback on its unique features. To learn more and to get started visit
