There’s 3-4 extensions there on two devices. One is a SIP Phone with two extensions registered and one is a ATA adapter with 1 or 2 extensions registered. It is a dynamic address but hasn’t changed and has been whitelisted in firewall and system admin > intrusion detection.
But randomly at different points it will block all registrations from that IP still, even though the IP hasn’t changed. But it doesn’t show up in any of the gui locations that its been whitelisted in.
So perhaps IP Tables is blocking it for some reason? As it seems like it would need to be a system process vs. a FreePBX plugin as its been white listed in those locations.
Does a simple reboot of the machine clear out the IP table bans or is there another process that does?
There were no power issues, IP changes, it will just randomly start blocking sometimes a few times a week others once a month. It ran 2 - 3 months initially with no issue
