Architecture
FreePBX deployment architecture
FreePBX manages the Asterisk configuration layer; the platform around it — firewall, backups, provisioning and monitoring — is what keeps it stable in production.
01 · Carrier edge
SIP trunksOutbound routesInbound DID routingTrunk failover order and DID-to-destination mapping documented per number range.
02 · Security layer
Responsive firewallTLS / SRTPAdmin ACLWeb administration restricted to management networks; intrusion detection tuned to avoid locking out valid endpoints.

FAQ
FreePBX questions we are asked
- Can FreePBX handle multi-site offices?
- Yes. Sites are usually connected over VPN with per-site outbound routes, local trunk breakout where regulation or cost requires it, and inter-site dialling by extension range.
- How are upgrades handled without downtime risk?
- Configuration is backed up first, the change is applied in a maintenance window, and a rollback path (snapshot or restore) is defined before touching the system.
- What causes call recording to fill the disk?
- Recording every call with no retention policy. We set retention by queue or extension class, move archives to separate storage, and alert on disk thresholds before they become outages.
- Do commercial modules matter?
- Only where they replace real engineering effort — for example endpoint management at scale. We flag which paid modules earn their cost in your environment and which do not.
