An upstream carrier had a failure on a portion of their network. They are re-routing their traffic internally.

This may have caused some intermittent inbound calls for a small number of customers behind certain NATs which do not like re-routing/changes. This should be VERY isolated since it's only a small % on an extremely large network so it's likely you won't see any issues at all.

They are working to re-balance traffic and any intermittent errors will be eliminated once that happens.

If anything changes or we get additional information, we'll post it here.


On a related note, the firmware upgrade being pushed out today will help the ATA better deal with errors like this since it responds to "multiple invites" in a more consistent way when stuff is re-routed around problems. This will make the ATAs less likely to interpret errors like this as a complete call failure and send that signal upstream to generate a disconnected message.

Deleted question about the upgrade - details from Tim in the other thread.
