The appliance PBX,
reborn.

PhonixPBX is the open-source successor of AskoziaPBX: a complete telephone system built on Asterisk 22 and Alpine Linux, managed from a clean web interface. Flash it on a Raspberry Pi, boot it on a PC, or run it as a container — it is up and taking calls in minutes.

Features

Everything a small office PBX needs

Phones & providers

PJSIP, IAX and external phones, plus SIP and IAX trunks with registration — set up in a few clicks.

Dialplan without the pain

Applications, call groups, transfers, feature codes and call parking. Print the whole dialplan on one page.

Voicemail & conferencing

Voicemail with voicemail-to-email, ConfBridge conference rooms, music on hold and custom greetings.

Live status

Secure by default

nftables firewall, HTTPS with Let's Encrypt (ACME), TLS and SRTP for PJSIP, argon2-hashed credentials.

Updates you can trust

Signed firmware updates on A/B system slots with automatic rollback and a read-only squashfs root.

API & metrics

REST API with bearer tokens, Prometheus metrics at /api/v1/metrics and a console menu for the basics.

Speaks your language

The web interface ships in 13 languages, from English and German to Portuguese (BR), Russian and Japanese.
