3CX Blacklisted SIP Gateway IP

[SRCMike]

Just looking to see if anyone has encountered one of their SIP Gateway IP's being blacklisted in 3CX before for failed authentications, when nothing has changed.

HI I have seen this before i simply added the IP to the white list.

I've had some ATA's do this in the past. I added the entire local LAN to the whitelist. It's much easier than trying to track down why it happens on occasion.

Same here, had to add local LAN to whitelist.
Also my home IP address where I often use 3cx android, ended up on blacklist for unknown reason.
