PTI, a Pittsburgh-based technical institute, switched from a SIP-based call center to Twilio's Elastic SIP Trunking in 2015, enabling them to scale their communications hub and improve security. The move was sparked by a school art show project in 2012 where PTI used Twilio's SMS API to build a simple app, planting the seed for future innovation. With Twilio, PTI gained a reliable connection, reduced latency issues, and improved security, allowing them to integrate their CRM with live chat and enable staff to answer student questions via text message. The switch has enabled PTI to revolutionize its communication channels, meeting students where they feel most comfortable communicating - through mobile devices.
