Note: You can enter up to four NTP servers in your network, and press <Enter>. For example:
NTP Server #1: [pool.ntp.org]: 192.167.2.11 ↵
NTP Server #2: [pool.ntp.org]: 192.167.2.12 ↵
NTP Server #3: [pool.ntp.org]: 0.0.0.0 ↵
NTP Server #4: [pool.ntp.org]: 0.0.0.0 ↵
You can enter up to four NTP servers. If you have less than four NTP servers, enter the IP address(es) for the NTP servers that you have, and then enter 0.0.0.0 for the remaining NTP entries.
If you do not have your own NTP server, and the Aastra CNX has Internet connectivity, you may use the default server entry of pool.ntp.org.
Aastra Telecom strongly recommends the use of NTP servers, either your own or the default servers. NTP servers avoid clock slippage and inconsistent conference start times on the Aastra CNX. However, you may completely disable the NTP server feature by setting the IP address of all four servers to 0.0.0.0.
