Call Recording FTP Server — SUPERSEDED

This document is historical. The Switchvox call-recording offload no longer
runs on a standalone ProFTPD/SFTP host writing to local disk. As of 2026-06-10
the PBX uploads over SFTP to the SFTPGo accessory (heatwave-sftp), which
stores objects directly in Cloudflare R2.

Current documentation → SFTPGO.md — architecture, the pbx and
pbx-backup users, R2 buckets, Switchvox configuration, the WebAdmin UI, the SMTP
notifier, credentials, and the operator runbook.
