Our analysis

In its 2019 SIP Trunking North America Scorecard, IHS Markit analyzed and ranked the top SIP trunking providers in North America. For the fourth year in a row, CenturyLink leads the SIP trunking market with solid growth and the largest installed base of trunks. CenturyLink has done extensive work over the past two years bringing together its assets with those of Level 3, a company it acquired in 2017, to build a market-leading service portfolio and customer base.

In this year’s scorecard, Twilio made another jump to the second-ranked position because of its strong financial score and the continued growth of its installed base. Twilio has been a market disruptor with its Elastic SIP Trunking service, which has grown to attain a sizeable installed base. The strong growth of Twilio’s Elastic SIP Trunking service reflects the widespread appeal of flexible consumption-based pricing.

Just a few years ago, there was little differentiation in the SIP trunking market. Fast forward to today, and there is a stark difference between traditional trunking services and the new on-demand trunks. Traditional trunking remains grounded in the old world of contracting for voice networking. In contrast, with on-demand trunks, customers simply pay for what they use and never need to worry about capacity planning.
