I am building my UCCE lab in a virtual environment. I am following the notes from the ICM staging guide. So far I have configured UCM and registered 3 phones, configured the same as my PIM1 and a CVP 7.0 as PIM2 in a composite PG simplex environment. My issue is none of my pims do go active. I have checked my hostnames and connection ports in both cvp and setup. Can some experts suggest me how to trouble shoot these issues?
