Mitel 6930 IP - We received several 6930 when migrating from Mitel that we were told were 100% compatible with all Ring Central Features. We provisioned them using the MAC Address originally and had Key Template Layouts setup for these phones.
As of today they no longer support Key Template Layouts and I was told they are not fully supported right now but will be. I say as of today as this is when users first brought it to my attention. Several phones still had the old settings this morning as well and were working (they grab the new settings on reboot and lose their custom mappings)
These phones have lost their speed dial settings which were in use. I am unable to create new ones because of the change.
