When a SIP CO line 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. For more information, refer to "15.1.24 Private
Network Features—VoIP (Voice over Internet Protocol)—Automatic Rerouting of VoIP Calls to Public CO
Lines".
