Case Study: Lifesize achieves fastest‑growing product and rapid global scale with Twilio Elastic SIP Trunking

Fastest Growing Product in Lifesize's History Powered by Elastic Sip Trunking

Lifesize, a global video conferencing leader with more than 15,000 customers, shifted from a hardware‑first model to a SaaS offering to meet growing demand for flexible, web‑based conferencing. To deliver Lifesize Cloud worldwide it needed scalable PSTN/dial‑in connectivity but couldn’t feasibly manage local carrier contracts, number provisioning, and regulatory requirements in 100+ countries.

By using Twilio Elastic SIP Trunking and a modular, fault‑tolerant architecture, Lifesize quickly provisioned global numbers and trunks via API, scaled capacity with pay‑as‑you‑go pricing, and added country coverage in days. The result: accelerated time‑to‑market, shorter sales cycles, improved NPS, onboarding in dozens of countries in under a month, and Lifesize Cloud becoming the fastest‑growing product in the company’s history.
