Twilio launches Elastic SIP Trunking, courts more enterprises

A beta of Elastic SIP Trunking could allow Twilio to broaden its land and expand strategy in corporations.

Twilio launched the beta of Twilio Elastic SIP Trunking in a move that could get the company's messaging platform into more enterprise accounts.

SIP (Session Initiation Protocol) is a communications protocol used to send voice and video over Internet Protocol (IP) networks.

Twilio provides SMS and messaging technology and APIs for companies like Uber and Airbnb and has expanded into more enterprise accounts. Twilio Elastic SIP Trunking breaks apart Twilio's bundle of service and allows enterprises to fit the company's technology into existing telecom stacks. Twilio charges based on usage without long-term contracts.

Jeff Lawson, CEO of Twilio, said the SIP effort is a way to offer just a part of the overall service and charge less. "Enterprises may need just a part of Twilio because they've invested in a stack already," said Lawson.

Indeed, Twilio's move could allow it to land and expand into more corporate accounts. Like Splunk and other next-gen enterprise IT players, Twilio has started from the bottom up with developers, but once a beachhead is formed the company grows wallet share. Twilio has used that playbook with customers such as Home Depot, Coca-Cola and Nordstrom.

Lifesize, the video conferencing unit of Logitech, is a reference customer for Twilio's SIP Trunking. Twilio has points of presence and phone numbers in 50 countries.

Among the key features:

  • Numbers on a SIP Trunk can send text messages in some markets.
  • Quality is measured to route calls to the best carrier. 
  • Call recording is available without additional hardware. 
  • Failover in case of an outage. 
  • Usage tracking.

Twilio said it will provide unlimited usage with fees as low as $0.004 per minute.
