SAN FRANCISCO, CA--(Marketwired - Mar 16, 2015) - Twilio, the leading cloud communications platform company, today announced the global availability of Twilio Elastic SIP Trunking along with an SLA and access to new enterprise features. Twilio Elastic SIP Trunking offers instant provisioning with contract-free and transparent pricing so enterprises can deploy SIP trunking in minutes and at a fraction of the cost previously possible. Additionally, Twilio uses the power of the cloud to deliver a highly resilient global architecture, with no capacity limits. Today's announcements bring the full power of the Twilio cloud communications platform to premise-based infrastructure, completely changing the way businesses of all sizes take advantage of SIP.

SIP trunking has been around for years, but a remarkable 80 percent of enterprises that need to provide PSTN connectivity to their on-premise infrastructure still use the legacy telecom approach of physical PRI connections. Current SIP trunking offerings can be painful to adopt, requiring extended contract negotiations, confusing pricing models and long deployment times. In short, existing SIP trunking solutions have not fulfilled on the promise of flexibility that software can enable, and have offered few compelling new capabilities compared to legacy PRI connections. 

Twilio Elastic SIP Trunking fundamentally changes what SIP trunking can do and how quickly it can be deployed. With Twilio, SIP trunking natively supports call recording, SMS and disaster recovery. Twilio Elastic SIP Trunking is available instantly with self-service provisioning and a transparent pricing model. Backed by an SLA and access to new enterprise security features such as private connections to the service (MPLS), encrypted media and signaling (SRTP/TLS) and support for emergency services calling (E911), businesses of any size can now deploy exactly what they need without the hassle and expense of previous options.

"Existing SIP trunking providers aren't giving customers the scale, flexibility, and ease of integration advantages that software can provide," said Jeff Lawson, co-founder and CEO of Twilio. "We built Twilio Elastic SIP Trunking to make it easier for any organization to migrate to cloud-based voice connectivity throughout the world. We can't wait to see what our customers will build."

Twilio's easily programmable communications stack can be used to replicate the on-premise IVR logic in the cloud, so in the event of a PBX or local connectivity outage, business service will continue with call flows dynamically re-routing to the cloud. Calls can also be recorded and stored in the cloud, with no expensive hardware costs or per user fees. IP Infrastructure can even be augmented with WebRTC calling, bringing the power of contextual in-app communications to traditional infrastructure without the need for hardware or software upgrades.

Twilio Elastic SIP Trunking features include:

• Instant, one-click provisioning of trunks for inbound numbers from 50 countries and outbound calling to every country in the world -- one contract, one interop.
• Numbers that can send and receive SMS and MMS by integrating the Twilio Messaging product (in select 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.
• Disaster recovery with TwiML scripting that lets you replicate on-premise IP-PBX in case of outages.
• 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.
• Backed by an SLA that provides a 10 percent or more service credit if Twilio falls below the SIP trunking service availability commitment of 99.95 percent.

Early access is now available for the following enterprise features:

• Secure connections over MPLS or TLS/SRTP
• E911 support for emergency service access
• SIP Registration for extending connectivity to SIP phones

Twilio provides unlimited capacity with outbound per minute pricing as low as $0.004 per minute.

Also introduced today, Twilio Elastic SIP Trunking is accredited for deployment with Edgewater's market-leading Enterprise SBC (E-SBC), making it faster to deploy in enterprises. "Edgewater Networks is excited to work with Twilio as the unique ability to provision global SIP trunks on demand makes it possible to turn up new sites or countries with no lead time," said Dave Norman, CEO of Edgewater Networks. "Twilio's launch of on demand enterprise features like SRTP and SIP registration coupled with Edgewater Networks' ease of deployment, makes an ideal solution for companies needing secure, flexible enterprise communications."
