Elevated error rates for SIP/PSTN

This incident has been resolved.

It appears that SignalWire rolled back the change, and the errors have stopped. We are monitoring for any further issues.

SignalWire has confirmed that they made an unannounced change that's causing the problem, and they're working to revert it. We're also working on a quick production update to work around the issue if they can't revert quickly enough.

We're investigating elevated error rates from SignalWire when provisioning SIP/PSTN resources. If you're creating rooms with dial-in or dial-out enabled and it isn't absolutely necessary, you can remove those params from your room creation request to successfully create rooms.
