I made a softphone for Linux!
Softy is open source (AGPL-3.0) and runs on Linux. Download it from gitlab.com/softyphone/softy. Debian 13 package on the Releases page.
In the past I have used MicroSIP as a softphone on Linux, running under Wine. It worked well, but I wanted a softphone that was native to Linux.
With the advent of AI, I decided to see how hard it would be to port MicroSIP to Linux. It turned out to be mostly a rewrite, so I’m calling this project inspired by MicroSIP.
The goal of the project is to be a native Linux SIP softphone, suitable for everyday use.
I’ve been using it to make 2–3 calls a day for the last few weeks and it seems to work very well (for my needs). I use it with FreePBX 17 at my work.
Features:
- Multiple accounts simultaneously
- Configurable shortcut buttons (suitable for parking calls)
- Easy to see and switch between audio inputs and outputs
- UV meters for the mic and speaker
- Visual warning if you talk while still muted
- Transcribe calls using local whisper.cpp model, or an online service
- Clickable numbers in the transcript when it picks up IVR menu options
- Call recording
- First-class Linux app (tested under GNOME)
- Contacts list
- Popup on incoming calls
- Tested with FreePBX 17 (Asterisk 22); should work with any SIP server
I have made heavy use of AI to develop this, so treat it as beta and use it at your own risk. The source is open for anyone to check.
