Managing the Time and Date

Cisco IP phones obtain the time settings in one of three ways:
• NTP Server—When the phone boots up, it tries to contact the first Network
Time Protocol (NTP) server to get the time. The phone periodically
synchronizes its time with the NTP server. The synchronization period is
fixed at 1 hour. Between updates the phone tracks time with its internal clock.
• SIP Messages—Each SIP message (request or response) sent to the phone
could contain a Date header with the current time information. If the header
is present, the phone uses it to set its clock.
