Daily: Elevated error rates for SIP/PSTN
Affected components: SIP/PSTN
Timeline of updates
- investigating
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.
- identified
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.
- monitoring
It appears that SignalWire rolled back the change, and the errors have stopped. We are monitoring for any further issues.
- resolved
This incident has been resolved.
