Update
We've identified an issue with how Daily and SignalWire are negotiating audio codecs for incoming SIP/PSTN calls. We're working on an update that will change the default audio codec used between Daily and SignalWire to Opus.
We've identified an issue causing degraded ("broken up" or "choppy") audio between some Daily sessions and SignalWire SIP/PSTN endpoints. PSTN dialout and PIN dialin do not seem to be affected. SIP dialout seems to be moderately affected. PIN-less PSTN dialin and SIP dialin seem to be experiencing a much higher proportion of affected calls.

Investigating
We're investigating reports of poor quality audio for SIP/PSTN participants in some calls.
