Asterisk handles SIP and media. The API runs your call flows and configuration. PostgreSQL stores the state. Your team works in the web app.

One prebuilt image

Asterisk, API, web, embedded PostgreSQL and speech. Persist everything under /data.

A FEW GOOD QUESTIONS

Clear answers, straight from the project.

What is MunaSIP?

MunaSIP is an open-source Asterisk-based company PBX for small offices, designed around roughly 20 extensions. It includes an admin panel, visual IVR designer, browser softphone and employee portal.

What do I need to run it?

Use a Linux x86-64 server with Docker. The prebuilt image targets linux/amd64. The deployment guide recommends 2–4 vCPU and 4–8 GB RAM; neural speech runs on the server’s CPU. You also need persistent storage, a public hostname and the appropriate signalling and media ports.

Can I keep my SIP provider and desk phones?

MunaSIP supports registered and IP-based SIP trunks, multiple providers and route failover. Yealink, Fanvil and Grandstream provisioning profiles are documented. Check your provider’s transport, codecs, networking and device configuration before switching.

Does the softphone work on mobile?

The portal works in a mobile browser, but mobile browsers can suspend background tabs. Inbound calls with the screen off are unreliable. For dependable mobile reachability, use a compatible native SIP softphone with QR provisioning. MunaSIP does not ship a first-party mobile app.

Does everything work offline?

The PBX and your locally stored data run on your infrastructure. EMA provides offline Turkish speech after its models are built into the image. Edge Neural speech, including English, needs outbound internet access during generation. External SIP carriers and integrations have their own network requirements.

Can I use MunaSIP commercially or contribute?

Yes, the MIT license allows commercial use, modification and redistribution with the copyright notice. You can fork and adapt MunaSIP freely. Visit the official repository for current development and contribution guidance.
