Case Study: Harrow School achieves reliable, future-proof SIP communications with Mitel

Harrow School - Customer Case Study

Harrow School, a leading independent boys’ school in Middlesex, UK, serves 824 students across a 400‑acre campus. The school needed to move from legacy ISDN30 to SIP trunks for cost savings, better performance and future‑proof communications, and required managed, proactive monitoring and support to ensure reliable 24/7 operations.

Mitel (MiVoice Business and Mitel Performance Analytics) and partner Arden Telecom delivered a managed private cloud with SIP trunks, proactive 24/7 monitoring, secure remote device access and detailed voice‑quality data. Arden now detects and resolves network and voice issues before downtime, simplifies troubleshooting and protects Harrow’s telephony investment.
