Date and Time
The device's internal clock (date and time) can be set using one of the following methods:
■ | Manually (see Configuring Date and Time Manually) |
■ | Automatically synchronized using a third-party, remote Simple Network Time Protocol (SNTP) server (see Synchronizing Date and Time through SNTP) |
■ | Automatically synchronized using the SIP Date header (see Synchronizing Date and Time through SIP) |
■ | Automatically synchronized using the host's virtual PTP (Precision Time Protocol) device (see Synchronizing Date and Time through PTP) |
For automatic synchronization, NTP takes highest preference, and then SIP Date header
