I have a customer running all VVX 400 series phones. He would like to remove the DND function from some of them. I see in the Polycom forums that it is possible with UCS 5.1.1 and later, but need clarification if it can be done with behind a 7100. Disable or remove the DND Softkey - Polycom Community
Am i able to run UCS 5.1.1 safely on these phones?
What file would need to be modified to accomplish this on a per phone basis?
Thanks
