23 ตุลาคม 2552 16:48the network team verified that traffic from port 443 and 5061 are allowed to come in, any other ports need to be open for this???
24 ตุลาคม 2552 16:06If your Edge is in a perimeter network than you need also ports from your dmz to the inside network and vice versa. Look at the deployment guide for all necessary ports.
Hope that helps.
