An engineer is receiving several Cisco TMS email alerts for system phonebooks that are not updating. Which menu path should the engineer use to suppress these Cisco TMS email alerts?

'Clear this ticket' dismisses a single existing ticket instance but does not suppress future alerts of the same type.

SMTP settings control the mail server configuration for TMS, not which alert types generate email notifications.

Cisco TMS uses a ticket system to track infrastructure issues, and 'Manage ticket error levels' lets administrators adjust the severity level of individual ticket types. Lowering the severity of phonebook-related tickets to a non-alerting level effectively suppresses the associated email notifications without disabling all alerts globally.

'Ticket management' is used for reviewing and managing existing tickets, not for adjusting alert suppression rules.

'Email notification settings' controls which users receive emails, not which ticket types trigger them.
