DESKTOP SOFTPHONE FOR SIP ROUTERS
Aqorin Phone
A modern, lightweight, cross-platform SIP softphone built with .NET. No in-app accounts, no ecosystem, no clutter. Add your SIP credentials and call.
Installer downloads require the same AQORIN site login as the main page. The app itself only needs your SIP credentials.
CALLING WORKFLOW
Just enough phone interface, without the ceremony.
Dial numbers, answer calls, mute, hold, choose speaker output, and keep your contacts and recent calls close.
Incoming calls
Active calls
Core controls stay visible.
Mute, hold, speaker, and hang up are available during the call, with no inactive controls cluttering the screen.
History
Recent calls are preserved.
Incoming, outgoing, missed, and ended calls are kept for later reference, with a clear option when you want a clean list.
ROUTER AND PBX FRIENDLY
Built for common home and office SIP setups.
Aqorin Phone is designed around standard SIP registration, so it can connect to router-hosted phone accounts and PBX extensions that expose SIP credentials. Use a router profile when available, or enter the registrar, port, transport, username, password, and display name manually.
FRITZ!Box
Router LAN registrars
Local PBX extensions
UDP and TCP profiles
Custom SIP hosts
Saved audio devices
OPEN SOURCE
Built in the open with .NET, Avalonia, SIPSorcery, and PortAudio.
Aqorin Phone uses standard SIP signaling and RTP audio instead of router-specific management APIs. Clone it, fork it, inspect it, or adapt it for your own PBX setup.
EVERYDAY PHONE TOOLS
Contacts
Add frequently called people and internal extensions, switch between favorites and all contacts, then place calls from the list.
Audio preferences
Choose microphone, speaker, ringing device, and call behavior without leaving the app.
Light and dark themes
Use a bright desktop-friendly layout during the day or switch to a darker phone-console look for low-light work.
Account persistence
Saved SIP settings and call history remain available across restarts on the same machine.
