Solved T28P + SBC + 3CX in Cloud

[Glen.c]

Set up is:-

3CX in LightSail
Site has an SBC
3 x T28's

So are T28's no longer usable? They show up in 3cx but attempting to provision them does nothing but a major thing with them seems to be that once you install firmware version 2.73.0.60 it seems to break the web server of the phone unless you manually go to the phone and disable https 443. You cannot get into the web gui on either port 80 or 443 if 443 is enabled. Once i disable 443 i can get into the web server but the phones cannot get provisioned.

is this related to that letsencrypt root cert thing a few months ago?

Did you turn off that setting?

Where is that setting? I turned off 443 and i was able to get back into web gui but cant provision the phones because the system is in the cloud and needs ssl.

 

[cobaltit]

SSL for the phone UI has nothing to do with the ability to provision the phones.

The 3CX setting is at the bottom of the anti-hacking page.

Worked like a charm, thank you very much cobaltit.
