Case Study: Santa Fe Irrigation District achieves disaster‑proof, VPN‑backed phone continuity with AireSpring SIP Trunking

How AireSpring helped the Santa Fe Irrigation District create business continuity for their telecommunications infrastructure

The Santa Fe Irrigation District (SFID) is a potable and recycled water provider in Northern San Diego County serving about 20,000 customers with approximately 7,300 services. SFID needed a disaster‑proof, flexible backup for its phone system without relocating equipment or changing longstanding phone numbers; after other carriers’ offers proved incompatible, they engaged AireSpring and explored a SIP Trunking solution.

AireSpring implemented SIP Trunking with VPN routing through a nearby colocation center, allowing SFID to retain its existing phone infrastructure and numbers while adding a secure, off‑site backup. AireSpring was the only vendor able to meet SFID’s criteria at a reasonable price, delivering a hardened communications layer that fortifies SFID’s Disaster Recovery plan and helps protect continuous water service for the community.
