Automatic Rerouting of VoIP Calls to Public CO Lines

When a VoIP call cannot be completed successfully, the PBX can automatically attempt to make the call using a public CO line instead. This provides a backup method of making calls in cases when IP network transmission cannot be completed successfully.
