Brandon763,
The only way to get the IP Address is through Operations > Show IP Device Status or the DHCP service if it is used for the phones. I was just trying to explain that the information from the SA&D could be downloaded and combined together to provide a more comprehensive look at your phones: Type, Version, MAC, etc..
I think there may be a log file that would have the IP Addresses of the phones, but I would need access to a MiVO-250 to search for it, and as of late I have only been working on 3300 to build my skills up on that system.
There is also the command that is sent to the system for the Show IP Device Status that could be captured with Wireshark. There is also the System Commands module under SA&D that will provide you some commands that may get you that information as well; look at Networking as well as Phone and Device Information.
Other than that I don't know what you could do to get just the Extension, MAC, and IP Address. I haven't used a 3rd-party DHCP server on any of our systems since the MiVO-250 got the embedded DHCP.
Sorry,
TE
