Monitoring
One of Comcast’s large backbone network partners had a fiber cut that we believe is also impacting other providers. Comcast continues to work on resolving the fiber cut. Routing voice calls over your non Comcast backup connection does restore the audio issues.

Identified
The one way audio issue has been isolated to the Comcast network. As Comcast works to resolve the network issues, SimpleVoIP has confirmed the audio issues will be resolved if phones are moved over to a backup WAN link from a different service provider.
