I have a new CM6.3 with a G450. It hasn't been turned up but I am trying to pre test with a MM717 in the G450, amphenol cable connecting it to a patch panel and using an 8410 digital phone. I get power on the phone and all the lights will flash once, then I optomize the speaker then the test light flashed and I get no dial tone. I tried reversing the pairs on the back of the patch panel but same results. Any ideas?
