Zoom on Polycom VVX450 randomly disconnecting calls and Uploading 1 of 1 core files

[FHMaurice]

This appears to be happening only to my remote users and it has happened to me.  I was on a call and then wham, the phone went out and it took 10 minutes to reboot (no exaggeration for purposes of getting faster answers).  One of my teammates believes if there is a glitch in the Matrix (aka the wifi) goes out, then the phone restarts.  However, I have been able to disprove that since my phone is not using POE I simply pulled the ethernet cord, waited and then plugged it back in.  It did not reboot.  Is there a way for me to get a log of what is happening on the phone. I am an admin so I should be able to do most things but I don't know what I don't know.  Also, with that in mind, is there a way to make sure that updates don't get installed until say after 3:00 AM the next morning so that no one gets disconnected?  Thank you in advance for any help you can provide.  Oh and PS. I unplugged the phone just to see if there was really any updating to it and it took 10 minutes again stating Uploading 1 of 1 core files.

hi FHMaurice,

You can control what firmware version your phones use and when firmware updates occur.  This means that the phones will not update firmware automatically or the updating can be scheduled for non-working hours.  Please see zoom support articles.
