Dialer & PBX Customization

FreePBX Customization

FreePBX is the most widely deployed PBX management interface in the world — and also the most widely under-configured. We take FreePBX installs from 'it works' to 'it survives': custom modules in PHP for features your business needs, UCP extensions so end users get the self-service portal they expect, module hardening, and the less-fun work like backup strategies, database maintenance, and upgrade paths that don't take the phones down for half a day. Our FreePBX work also covers integrations with CRMs, paging systems, video intercoms, and anything else that needs to talk to Asterisk through a polished UI.

Who it's for

  • Businesses running FreePBX who've outgrown the default modules
  • MSPs managing fleets of FreePBX deployments for SMB clients
  • Teams needing custom features surfaced through the FreePBX admin UI
  • Organizations wanting FreePBX hardened for production with proper HA

Our approach

  1. 1Review the module inventory — uninstall what's dormant, upgrade what's stale
  2. 2Build custom modules the FreePBX way — hooks, BMO object methods, UCP widgets
  3. 3Keep the customization in version control so upgrades don't wipe your work
  4. 4Deploy in HA pairs when uptime matters — active/standby with DRBD or PG replication
  5. 5Integrate with your existing monitoring rather than rolling yet another stack
