Case Study: San Diego State University achieves 4X maintenance savings and resilient handling of 200,000+ weekly calls with OpenText CX-E Voice

San Diego State University transforms voice communications

San Diego State University, a public research institution with about 34,000 students and 9,600 faculty and staff, faced an urgent telecom challenge when its legacy Octel Aria voicemail system reached end-of-life. The university needed a next-generation voice platform that could reliably handle up to 200,000 calls per week, integrate with existing telephony and Google Gmail, support mobility and business-process automation, and require minimal retraining.

SDSU deployed OpenText CX-E Voice, using its Octel‑compatible TUI for a smooth transition and a redundant architecture (three call servers plus a system server) for high availability. The solution enabled unified messaging with Gmail, a speech-enabled directory and improved caller experience, delivered 4× savings in maintenance, and now reliably processes 200,000+ calls per week while providing a platform for future productivity features.
