SMB Blacklist

[louivoip]

Is there a way to contact 3CX to un blacklist an IP. Set up router phone for customer forgot to uncheck Block remote in extension options. Taken it off now. It is a singe phone in standalone office so no other phones to register it through.

Would registering a different phone/different mac address for this user with the same external ip address register

You cant provision an phone without sbc. Thats why its blocked now. The blacklist will reset after 24 hours but keep in mind to reset the phone and provision it over an sbc (or use an routerphone).

The phone used is a Yealink T42U router phone
