Hello, I run a small business in Brazil and I'm testing 3CX with two units of the T21P E2. It turns out that I really like this phone, it's cheap and the loudspeaker function is great for us. I would like to know if someone can tell me if this phone will continue to be supported by the 3CX phone system. I'm asking this because, although everything seems to work fine, the management console is showing messages like "unsupported" after provisioning on the newest firmware. Thanks for the help!
