We have a bunch of remote phones on VPN but they weren’t getting the right time until the WAN IP was whitelisted. As soon as I did that they sorted themselves out. Any ideas why? I didn’t think the WAN IP would matter. They register online OK other than that.
The phones are setup to get their own time individually from whatever ntp server is set in the template being used in the endpoint manager. So each phone has to be able to hit that NTP server.
Where are you whitelisting the WAN IP?
Hi Jason, I’m whitelisting the WAN IP in the distro firewall. It’s picking up the time from ‘Primary Time Server’, set in the EPM template as the server IP address, which it got immediately once the WAN IP was whitelisted but not before (over VPN), or so it was in this case.
