We have an IP Office IP 406 DS running version 3.0(59) and I can't find any info as to the significance of the "DS" in the model name. I am researching our options to upgrade this to the latest version 5 firmware as we want to use some of the latest features.
What is the "DS" version, and what will it take to bring this unit up to the current level?
Thanks much,
Tom
