I'm trying to add a centralized vm to a new s8300/g350 (CM4.0.1) DCS site. I cannot add the rem-vm hunt group to the CM4.0.1. When I add the centralized vm ext int the 2nd page of the hunt group form, i get "extension must be an off-switch (UDP) extension". Troubleshooting, i find that i cannot dial any dcs node extensions... the uniform-dial form is populated with appropriate matching extension, insert, etc.. the aar ana and route-pattern also look good. what is missing?
