I have run into a new problem. We have several users that work remotely and use a 4621 IP phone. They were all able to connect properly to our phone system and work without any issues. However, a new vulnerability came up when we did our monthly PCI scan. It is an issue which requires that we disable aggressive mode on the firewall in order to be compliant.I disabled aggressive mode and the phones no longer connect. I went into the phone settings and can't find a way to set the phone to main mode. Has anyone run into this issue?
Thanks!
