A Twilio Case Study
PhoneUnite, a Pittsburgh-based startup (founded 2012), provides hosted PBX services that integrate businesses’ inbound and outbound calling. While initially designed to route calls to mobile devices, customers still wanted traditional desk phones, so PhoneUnite needed a reliable, scalable, pay-as-you-go communications provider to support rapid growth without over-investing in capacity.
PhoneUnite chose Twilio SIP, using Twilio’s API to simplify SIP deployment, avoid common implementation pitfalls, and scale on demand. The switch delivered a future-proof platform with easier maintenance and the flexibility to add features — including auto-attendants, unlimited extensions and call trees, call queues, voicemail transcription, an iPhone app, and advanced reporting — while keeping costs aligned with usage.
