Windows status
SIPdia for Windows is not available yet. There is no code for this platform in the SIPdia repository and no release date. This page explains what a SIP softphone on Windows involves so you can plan, and where SIPdia stands. Nothing here is a download.What a SIP softphone for Windows should do
- Transports and encryption. UDP, TCP and TLS for signaling, SRTP for media. TLS matters on Windows laptops that roam between office, home and public Wi-Fi.
- Audio handling. Separate microphone, speaker and ringer devices, echo cancellation, and correct behaviour when a USB headset is unplugged mid-call.
- NAT traversal. STUN and ICE, and symmetric RTP, so audio works behind home routers without port forwarding.
- Codecs. Opus for quality on poor links, and G.711, which most PBXs and providers support. G.722 adds wideband audio on many desk phones; G.729 saves bandwidth but is not offered by every client or server. The codec used on each call depends on what the server allows.
- Call handling. Hold, blind and attended transfer, several concurrent calls, DTMF via RTP events (RFC 4733).
- Accounts. Several SIP accounts registered at once, with a way to choose the outgoing account.
- Deployment. Silent installation and configuration for IT teams, Windows notifications, and startup at login.
- Privacy. Credentials stored in the Windows credential store, no telemetry you did not agree to.
Where SIPdia stands on Windows
SIPdia today ships for macOS 14 and later and for iOS and iPadOS 17 and later. Both apps share one call engine (baresip 4.12 with Opus and OpenSSL), one settings format and one design. The engine itself is portable, which is what makes other platforms practical, but a Windows app does not exist yet and no release date is announced.
When a Windows release is published, this page will carry the system requirements, package type, version and download link, and the download center will show it alongside the Mac and iPhone apps. Until then there is no download, no beta and no sign-up list.
If you need a SIP softphone on Windows now, use the checklist above to evaluate the options available today. Our guides on SIP accounts, transports and troubleshooting apply to any standards-based SIP client.
Windows FAQ
Is SIPdia available for Windows?
No. There is no Windows app and no release date. The Mac and iPhone/iPad apps exist; Windows, Linux and Android are planned.
Will the Windows version have the same features?
That is the intent, since the apps share one call engine, but nothing is promised until a release exists. Features will be listed on this page once verified.
What should a SIP softphone for Windows support?
At minimum: UDP, TCP and TLS transports; SRTP; Opus and G.711; STUN and ICE for NAT; selectable audio devices with echo cancellation; and Windows notifications for incoming calls. For office use, add hold, transfer and multiple accounts.
Which Windows versions matter?
Windows 10 and Windows 11 are the versions in common use. Check whether a softphone supports both and whether it offers an installer suitable for managed deployment (MSI or MSIX).
