Good evening,

We faced with the problem when reprovision button (3CX Web -> Phones) doesn't work.

We use TLS (Snom Phone Web -> Identity 1 -> Outbound proxy -> [FDQN]..3cx.eu:5061;transport=tls).

With Outbound proxy -> [FDQN]..3cx.eu:5060 everything is fine and works well.

Is there any solution? Thank You
 
I think it is clear that TCP 5061 must be enabled and NATted to your 3CX host. Try telnet to the FQDN:5061
Second, as we provision this field within 24h we will set it back to defaults.

Now, as you use a 3CX FQDN, have you copied and pasted the TLS information in the security tab?
(Note, those certs run out in 90 days and will be re-issued and you need to copy past them again, including sip server restart!)
 
Dear Stefan, yes, everything fine with 5061 port.

Now, as you use a 3CX FQDN, have you copied and p asted the TLS information in the security tab

What did you mean copy/paste for TLS? We made zero ssl certificate for ethernet interface and paste it to TLS tab.
Phone work fine with TLS outbound proxy, fine except reprovision button.

as the phone does not trust the HTTPs connection and will give you an exception! Review the Snom logs (debug level) and take it from there how to resolve.
