Today I finished configuring an IPSEC tunnel to the office so that I could install a Cisco IP phone at the house. Now when I'm working from home people don't have to track me down on my mobile. One of the neatest things about IP Telephony is that I have have multiple phones in different locations that all have my extension so when I get a call it rings at my desk and at home.
Now as soon as I get some routing fixed at the office I will be able to use the data port on the phone and not have to use the VPN client to get in any longer. I love being an IP engineer.
