Mac
Not yet: Push notifications for incoming calls
SIPdia must be open to receive calls. On iPhone the app unregisters about 20 seconds after leaving the foreground, so calls go to voicemail or forwarding. Missed-call notifications are shown locally.SIPdia on macOS

Made for the way a Mac works
- Floating incoming-call window that appears on every Space and over full-screen apps, so you can answer without hunting for the window.
- Menu bar icon. Close the window and SIPdia keeps running and registered. Quit from the menu bar when you want it gone.
- Audio device selection for microphone, speaker and ringer, plus open at login.
- Keyboard shortcuts: Answer ⇧⌘A, Hang up ⇧⌘E, Mute ⇧⌘M, Hold ⇧⌘H, Record ⇧⌘R. Type digits during a call to send keypad tones.
- Sandboxed and notarized. The app runs in the macOS App Sandbox. Direct downloads are notarized by Apple; the Mac App Store build uses the same entitlements.
- Recordings are WAV files in Music > Call Recordings by default, or any folder you pick.
How to connect a SIP account on macOS
- Open SIPdia and sign in with Apple or Google. Sign-in is required before any SIP account registers.
- Go to Account. Enter the Server address (add
:portif your server does not use the default), choose the Transport (UDP, TCP or TLS), and enter the Username and Password. On a PBX the username is the extension number. - Open Advanced only if your provider lists a separate Domain, Outbound proxy or Auth username, or if you need a STUN server and ICE because you are behind a router.
- Click Save and Register. The dot in the sidebar turns green when the server accepts the registration.
- Allow the microphone, local network and notification prompts.
- To add another account, click Add Account and repeat. The free plan includes one account; more accounts need SIPdia Premium.

Forwarding and Do Not Disturb from the PBX
On a PBX with feature codes, such as Issabel or FreePBX, SIPdia dials short codes to turn forwarding and Do Not Disturb on at the server. Because the setting lives on the PBX, it keeps working when the Mac is asleep or off. The defaults match common Asterisk-based systems and can be changed under Settings > Feature Codes.
| Action | On | Off |
|---|---|---|
| Forward all calls | *72 + number | *73 |
| Forward when busy | *90 + number | *91 |
| Forward when not answered | *52 + number | *53 |
| Do Not Disturb | *78 | *79 |
| Voicemail | *97 |
Most SIP providers have no feature codes. Clear them in Settings and manage forwarding in the provider's portal instead. Forwarding and Do Not Disturb are part of SIPdia Premium.
Things to know before you rely on it
- The app must be running to receive calls. macOS offers no VoIP push for Mac apps, and a sleeping Mac misses calls.
- TLS needs a certificate from a public certificate authority. Self-signed PBX certificates are rejected.
- Codecs are Opus, G.711 ulaw and G.711 alaw. G.722 and G.729 are not included.
- Forwarding status shows what SIPdia last sent; changes made from a desk phone or the PBX panel do not appear in the app.
- Not for emergency calls. Whether emergency numbers work depends on your SIP provider.
macOS FAQ
Which Macs can run SIPdia?
Any Mac running macOS 14 (Sonoma) or later, Apple silicon or Intel. The release build is a universal binary.
Does SIPdia for Mac receive calls when the window is closed?
Yes, as long as the app is running. Closing the window leaves SIPdia in the menu bar. If you quit the app, or the Mac sleeps, calls are missed, so set Forward when not answered to a mobile number or voicemail.
Can I choose which microphone and speaker SIPdia uses?
Yes. Settings has separate pickers for the microphone, the speaker and the device that plays the ringtone. Echo cancellation and noise reduction come from macOS voice processing.
Where are SIP passwords stored on the Mac?
In the macOS Keychain. Account settings, call history and logs live in the app's sandbox container. Nothing is uploaded except the sign-in to your SIPdia account.
Why does the Mac ask for Local Network permission?
macOS asks before an app may talk to devices on your local network. If your PBX is on the office LAN, allow SIPdia under System Settings > Privacy & Security > Local Network, or registration fails with "Could not reach the server".
Can I use a self-signed certificate for TLS?
No. SIPdia for Mac accepts TLS certificates issued by a public certificate authority only. For a PBX with a self-signed certificate, use UDP or TCP over a VPN instead.
