SMB Pro account "An IP has been blacklisted"

[JohnnyBAT]

Hi, I am new to using this platform and one of the new phones that I just provisioned did not have the "Blocked remote tunnel connection" unchecked so now I cannot log into my admin portal. I am able to log in through another computer on a different public IP. I tried the Enterprise Version of this platform and I was able the "whitelist" the IP, but in the SMB Pro that I paid for does not have this option. What do I do?

My phones are not working by the way and if I hook them to another PUBLIC WAN connection, they come up.

If you try to add a router phone with old firmware it will fail. Update the phone first: https://www.3cx.com/docs/phone-firmwares/

SMB/Free has a 24 hour block and you need to wait. Disconnect and reset the phone then upgrade its firmware.

Or you can open a ticket with 3CX support or through your partner.

My phones are working today, but I am a little confused in why does1 phone being out of date takes down the entire system? My other phone were working fine before I tried to provision a new one.

It's detecting the repeated invalid login as a hack attempt and blocking the IP. The old firmware doesn't know the correct way to connect. It could just be one phone had older firmware, I've seen it vary on the same shipment.
