Polycom VVX411 Losing it's Server Credentials

[PatrickMcLeanCI]

I have several VVX411's deployed across several locations but I have 2 in particular in one location that seem to be losing their server ID and password credentials overnight. The provisioning server details stay in, but I'll get a call in the morning that the phones are offline and when I check they have a blank username and password field. After putting the credentials back in and rebooting they come up fine and stay working all day.

I believe the VPN connection is going offline every night, do the phones not reprovision automatically?

Ignore the provisioning entirely - this is not what causes the problem you described. The VPN is the important part here.

If you are using a VPN and it is going down, then this would be reason enough for the phones to stop working and require a reboot to come back. We have seen this happen with other brands like Yealink too, so it's a networking matter.

Find a way to either prevent the VPN from going down, or to reboot the phones automatically once a day.

You could also potentially reboot the switch on a daily schedule if you cannot fix the VPN issue.

Ok thank you I will look into it.
