I have issue with R20A working with Control4.
Issue is when we start call early media looks like Green screen.
From Control4 they telling that OS3.3.2 fixed it. And after i update project to OS3.3.2 R20A can't register to SIP.
I upgraded R20A to latest firmware and still can't register.
Tried another R20A with V3 firmware still no success.
I checked at version 3.3.0 and it still same. I found out that this problem only triggers when I use only C4 Wallpad. On some projects if I use with Akuvox wallpad and C4 wallpad same project this issue fixed sometime. I still don't know cause of this issue.
If you have T3 Wallpad with version 3.2.0 or higher then update or downgrade to 3.1.2. Control4 no longer update the T3 Wallpad I think they stopped at 3.1.2. I have tested on all Control4 OS versions and 3.1.2 was working fine hope it helps.
