HAPTER LACING AND ECEIVING ALLS
This information is cleared upon restarting or power cycling
the unit. To clear the Call Logging information manually, use
terminal emulation software to enter the command AT\N0.
Troubleshooting
What if no information is displayed? If you enter AT\N but
the Call Logging information is not displayed, you may not
have Caller ID provisioned on your ISDN line. If you would
like to use the Call Logging feature, contact your telephone
company and have them enable Caller ID. Note that there
may be an additional charge to add this service.
