Solved Incorrect date and time

[Luke Ivison]

Hi

For some reason all our phones have reset to 00:00am 01/01/1970 and im not sure how to get them back to the corrrect date and time. Our phones are Grandstream, Fanvil and Yealink and I have checked the NTP settings and they are correct. Has anyone ever come across this issue before?

Thanks
Luke

Your NTP settings, do there point to external ntp servers - if so have you block port udp 123 on the firewall (ntp port)

As the phones request the time, you need to allow the phone network access to the ntp servers

yes they point to external servers. I have just opened port number 123 UDP and it still is not working.

It seems that none of the settings i change in 3CX work when the phone downloads the configuration file. Could it have something to do with the fact that i cannot ping outside of my network from the VLAN

Need more info on your network setup - just some questions

Are the 3CX server and phones on the same vlan ?. If so can you ping the phones from the 3CX server ?

Can you access the internet from the vlan ?. If not you need to work out why

How have you configured the vlan for the phones / 3cx server

this issue is now resolved, the default gateway wrong wrong on the dhcp scope
