How can I change the IP Address for a StratagyES voicemail system?

I have the Administration tool (4.705), but I don't see anywhere where it references an IP Address. The only thing I see a reference to an IP Address of an email server, and one for the phone system itself.

We recently made some networking upgrades and have changed Gateways and Subnet IP information around and I probably need to update this system since I had to do the CIX boxes.

Thanks
