Click on the FAQs link above and go to software downloads. That will get you to the Tonido site.
I have an older DLS training course on there that I was given permission to share.
The answer to your question is Yes. You should be able to go into your Gateway settings in DLS and modify the IP addresses of the gateway boards. The numbers (such as 17-1 or 5-4) should stay the same and the templates and profiles should stay the same.
One of two things should happen. Either you will reboot the phones (which you can cheat and do by shutting down the POE on the switches and then turning it back up) and the DLS will give out the new information when the phone says hello to it at boot time, or you will have to select blocks of phones by what profile they are in and tell it to reapply the profiles. It should be good otherwise.
I would strongly caution you to be careful you don't change the IP addresses of your "back end" stuff, such as the processors, CC-A, CC-B, CC-C if you have APEs. There is a lot involved in that process and you could take the whole system down. It will also be challenging if you have APE processors at any of your remote sites, because you can't just go in and change those IP addresses either.
At my remote sites there is a VLAN and an IP block for each specific site, and all the phones, gateway boards, APEs, etc at each site all run on that same IP block. I *SO* wanted to avoid the complexity and hassles of making that kind of change that when we closed down one of our sites and moved the equipment to a new building I forced them to move the entire VLAN to that building so nothing would have to change....
Also note that you can register for access to the Unify Customer Support Portal at:
And from there you can download any documentation you need, new phone firmware, certain client software, etc. It can be a fun process to search for what you need, but it's on there. You might be able to find links to system software as well, but you will be blocked from downloading it. For whatever you download that is not documentation I also strongly suggest downloading and reading the release notes before you try to use anything, and make sure it is released for General Availability (GA).
Good Luck!
