Hello. I'm running ICP 3300 ver 7.0.21.5. The messagins sytem is 6510 version 2. We just upgraded from 1.5 DNIC integration. Since the upgrade a feature on our phones no longer work. I am able to set a button on our phones (5224/5340) to be a message waiting indication and they work to turn on and off the light on the button. However, when the light is on and you push the button it no longer calls the messaging system and asks for the password for the assigned ext. It does nothing when pushed. I'm wondering if it is a COS setting, but unable to find it.
Thanks!
Thanks!
