Choose Time source.
Choose one of the following:
• NTP—Choosing this setting makes it less likely that the time is synchronized
with Cisco CallManager, unless it also gets its time from the NTP server.
However, this method uses a standardized protocol and eliminates a
dependency on the Cisco CallManager server.
• CallManager—Synchronizing with the Cisco CallManager server making it
easier to compare logs from the Cisco CallManager server and the
DPA 7630/7610. You also do not need an NTP server if you use this option.
Restart the DPA 7630/7610.
The DPA 7630/7610 uses the time offset to define the time zone of the NTP or
Cisco CallManager servers if they are located in different time zones.
You set the time offset using seconds. For example, if the NTP server sends GMT
time and you are in PST, the offset is -8 hours, which is:
-8 (hours) x 60 (minutes) x 60 (seconds) = -28800 seconds
Therefore, in this example, enter -28800 in the time offset field.
If the NTP server reports using your local time, set the value to 0.
From the main menu, choose Configure.
Choose Network interface.
Choose Time offset.
Enter the appropriate value in seconds.
Restart the DPA 7630/7610.
