NTP is a standard protocol, so it doesn't really matter what kind of server it's running on. The ntp server allows ntp clients to get time from it by specifying the clients' IP addresses or an IP address range in the ntp server configuration. On the ntp client, in this case the Avaya server, you need to specify what ntp server it should contact to get the time. This is the part I'd like to learn. I can't find a place in the Avaya web interface to specify an ntp server. Does it exist? How do you set up an Avaya server as an ntp client? Thanks. -G.
