Explanation

SCCP phones obtain their time directly from the CUCM server's operating system clock, rather than querying an NTP server independently (unlike SIP phones). Therefore, configuring NTP for SCCP phones involves: (E) Configuring the NTP server in Cisco Unified OS Administration - this sets the OS-level time source for the CUCM publisher so its clock is accurate; and (A) Restarting the Unified Communications Manager services for the publisher and subscribers - this is required so that the updated time configuration takes effect and is propagated to SCCP phones. Configuring 'Phone NTP References' in CM Administration is only relevant for SIP phones, not SCCP.
