Can I import an existing FreePBX backup?

Yes. The Backup and Restore module accepts standard .tar backup archives. We document the version-compatibility considerations for upgrades from FreePBX 15 or 16.

Sangoma OS or Debian?

Debian 12 by default. Sangoma OS available by request but receives security updates on a slower cadence.

Sangoma sells commercial modules (Endpoint Manager, Class of Service, etc). You can license them yourself and install on our VPS. We do not bundle them.

WebRTC and chrome support?

FreePBX's WebRTC client works with current Chrome and Firefox. We document the WSS certificate and the chrome flags for testing.

VoIP SIP PBX Offshore

FreePBX Self-Host in Romania on Offshore VPS

FreePBX gives you the Asterisk power without writing dialplans by hand. For operators who want the GUI but need to keep the hosting outside the jurisdictions where their customers operate, a Romania-based FreePBX install hits the right balance: EU networking, no blanket data retention, NVMe storage for recordings, and prices that let a small ITSP break even at 50-100 extensions.

We implement, you ship. Async, documented, done in days.

Why FreePBX Over Bare Asterisk

Asterisk dialplans give you full control. FreePBX gives you a GUI that handles 80% of standard PBX builds without dropping to the dialplan: extensions, ring groups, IVRs, time conditions, queues, voicemail, conferences, SIP trunks. For most operators that is faster than maintaining custom dialplans, and the GUI is easier to delegate to junior admins.

The trade-off is some loss of fine control. Heavily customised dialplans (multi-tenant routing, complex CDR post-processing) still benefit from drop-to-shell editing.

Sizing for FreePBX 17

FreePBX 17 ships on Sangoma OS 7 or Debian 12. We default to Debian 12 because it gets security updates longer and integrates cleanly with our standard provisioning. Base install needs 30GB disk, 2GB RAM minimum. For production with 50-100 extensions plan 60-100GB NVMe, 4GB RAM, 2 vCPU. With call recording add 10-30GB per agent per month at scale.

The voicemail, MoH, recordings, and call logs all live on the same NVMe. Backup strategy: nightly snapshot to our backup volume, retention 14 days included.

PJSIP and Anti-Fraud

FreePBX 17 uses PJSIP by default. chan_sip is deprecated. We pre-install the Intrusion Detection module (fail2ban front-end) and set a 5-strike ban policy on SIP auth failures. Outbound dialplan has a CPS limit that prevents a compromised extension from initiating thousands of calls in seconds.

For Direct Inward System Access (DISA), we recommend disabling it entirely on customer-facing builds. If you must enable it, set a strong PIN and an outbound CPS cap.

SIP Trunking from Romania

Romanian DIDs are widely available through local carriers (we do not name specific suppliers). For international DIDs, most EU SIP wholesalers serve Bucharest cleanly. For US DIDs, some carriers route via Frankfurt with around 110ms additional one-way to NYC.

The FreePBX Trunks GUI handles PJSIP endpoint config for most wholesalers. We document the snippets for the common Tier 2 carriers.

Backup and Disaster Recovery

FreePBX has a built-in Backup and Restore module. We schedule nightly backups to a separate NVMe volume by default. For off-site DR, we offer optional replication to our Iceland or Finland location. Failover is manual (DNS change plus configuration restore) - true active-active multi-region FreePBX requires architectural work we scope per customer.
