Debug

Known issues

breakingIn version 2.0, the package was restructured from flat module to submodules. Old import paths (e.g., from signalwire import Voice) no longer work.

fix

Use from signalwire.voice import Voice

affects: >=2.0.0

gotchaThe library requires Twisted as an event loop; it does not work with asyncio out of the box. Running in an asyncio context may block or cause errors.

fix

Use Twisted's reactor or run in a separate thread.

affects: all

deprecatedThe signalwire.rest submodule for REST API calls is deprecated. Use signalwire.voice or signalwire.messaging methods instead.

fix

Use voice.calls.create() or messaging.send() instead of manual REST requests.

affects: >=2.0.0
