Awhile back i had switched about 12 polycom vvx300 phones over to a single switch and plugged the PCs into the vvx300s to limit the amount of ports used on the switch. However after doing so, whenever a user received a call the line would have a silence. no one would be able to hear each other (dead air). i ensured that ports 2222-2269 were open on the firewall. Is there a checklist or guide that i can access to show detailed steps and requirements to make that type of setup work?
Currently i switched everything back to the way it was and is now functioning. pc to switch and vvx300 to its own switch.
