Sangoma Leader in SIP Trunking for Small Businesses

Out of 29 SIP trunking companies examined in the Eastern Management Group’s latest SMB customer survey, none beat Sangoma. No vendor other than Sangoma received the highest possible ranking — four stars — in every customer satisfaction category.
If you’re not familiar with Sangoma — or maybe it’s been a while since you were — you may want to brush up… or catch up. The $100 million voice and UC solution provider is on a bit of a tear. Sangoma’s revenue has grown by 53% (CAGR) each year since 2017, and it got another healthy boost when it acquired Digium last September. Sangoma’s gross profit is around 60%, and the business currently spends a customer-comforting 18% of revenue on research and development.
Let’s Talk SIP
Apart from the company’s good financials, Sangoma further distinguishes itself in SIP trunking customer satisfaction. In Eastern Management Group’s “2019 SMB SIP Trunking Customer Satisfaction” survey, no competitor beat Sangoma, which stands at the pinnacle of the satisfaction leader board.
The Eastern Management Group’s 2019 satisfaction survey of 3,000 IT managers shows a side-by-side comparison of 29 SIP trunk providers. SMB customers (from one to 500 employees) evaluated their SIP vendors on six Customer Satisfaction Measurements under the headings of product, vendor experience, and customer delight.

About Sangoma
Sangoma is one of the scores of providers in the $14.4 billion (2018) SIP trunk market — a market that’s growing 7% yearly — and will continue doing so. The SIP market itself is catapulted by cloud growth, enterprise branch office openings, high PSTN prices, and the inevitable POTS end of life, which are addressed in the Eastern Management Group report "2018-2024 SIP Market 7-Year Forecast and Analysis."
Sangoma is an established provider of hardware and software that drives IP communications systems for telecom and datacom applications. The company, which launched in 1984, sells to SMBs and carriers in 150 countries. Well-known Digium is a Sangoma subsidiary, making Sangoma the primary developer and sponsor of the open-source Asterisk project.

Sangoma’s largest customer cohort is businesses with 11 to 50 employees; this may account for a third of Sangoma’s SIP customer base.
