How to use SipWarp

SipWarp is a Windows phone for a SIP account. You place and answer calls on this computer. Contacts can live on this PC, or in a CardDAV address book that your cell phone shares.

Do these in order the first time:

1. Connect an account. voip.ms is the walkthrough. Twilio, Telnyx, Anveo, and IPComms are on that same page.
2. Pick the microphone, speaker, and ring device. Make a test call.
3. If the call rings but you hear nothing, set RTP ports and a STUN server.
4. Import a contact file, or connect CardDAV so the same names show on your phone.

Account is the button at the bottom of the window. Settings is next to it. Help is this book.

Your password, contacts, and settings stay in %APPDATA%\SipWarp. Uninstalling the program does not delete that folder.
