My Polycom VVX phones (mostly VVX 450 and one VVX 250) display "Line unregistered" errors throughout the day when using end-to-end encryption with OnSIP (cloud PBX provider). When end-to-end encryption is not enabled on OnSIP's end, the errors do not appear. The phones then re-register within 15 - 20 secs. However, the lines never actually unregister. You can talk through such an unregister event and you can always reach a line that just flashed the error. I assumed it's my Sonicwall NSA 5600 firewall, but I have moved these phones to two completely different networks with verious routers, PoE switches, and even different internet providers. The same errors occur and we can always talk or reach the phones even as the error appears of the display. Neither Polycom support not OnSIP support can figure out what's going on. The phone themselves display a SSL_get error with unknown reason each time this occurs. Has anybody had this problem? I know there are unregister posts , but those people actually have their units unregister and are unable to place calls or they drop in the middle of an active call. That is not the case here.

Hello @M the D ,
Welcome to the Poly Community.
Both the communities Must Read First or Read 1st and if available the FAQ reference the basic minimum information a new or follow-up post should contain.
This ensures the questions having to be asked are limited and any new or follow-up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.
Unfortunately, your post fell a bit short of the above-explained requirements and we kindly ask you, therefore, to ensure to read these sections and ensure a reply (not Edit!) provides as much detail as possible
Please ensure you familiarise yourself with the FAQs listed in my signature for your convenience.
The best and quickest way forward is to contact our Support organisation as the community is run by volunteers only.

Notice: I am an HP Poly employee but all replies within the community are done as a volunteer outside of my day role.
