i just upgraded a 7100 to v4.70. with 4 IP phones. The issue I'm having is with the remote IP phones. They currently have dynamic IP address at the 2 remote locations(2 IP phones @ each location.) that being said I've had to log in to the system everyday to add the new IP to the white list parameters for the phones to register & work. Yes unfortunately the phones are going across the public internet with no VPN tunnel or anything. I dont have time to do this every morning & the customer is not happy with this situation currently. Is their any thing else i can do? or just down grade the software to an earlier version?

thanks guys

Just disable the whitelist for those extensions in the ip extension setup area

what MMC is that nameless? thanks

The same one where you configure the login id and password, codec setting, etc
