Phones no longer support Let Encrypt

[tom-nbb]

I wanted to note, the phones DO support Lets Encrypt, but you must lower the key length from 4096 bits to 2048 bits. This is described on the official FreePBX forum.

I would love to see this fixed because the solution is a hack and causes FreePBX to complain that you have modified files.
