Trustane

Trustane is managed VICIdial hosting on a VPS or on dedicated cores. A customer orders a server, picks the region closest to the numbers they call, and the VICIdial logins appear in the Trustane portal a few minutes later. From then on Trustane handles the patching, the backups and the monitoring. Each server runs a chosen, tested VICIdial revision, hardened and patched, with TLS. Backups are held off the server nightly, and recordings are compressed at the source with retention enforced. The web console shows every server live in one place, with wallboards and alerts for callers waiting, drops at 3% or more, leads running out and screens that stop reporting. Customers bring their own carrier with no markup and pay by the hour, capped monthly, with no per-agent licence. VICIdial is a trademark of its owner. Trustane is an independent hosting provider.
