Is it that realistic though that 130 phones have to be statically set? That is a lot of phones to set. I will follow your suggestions and see how we make out. Do you think that setting to default and reloading the database could clear the issue? The MBU settings say no tagging and to vlan identified. The phone port however in the switch is untagged for vlan 5. We added the tagging and vlan 5 on the mbu and made the same adjustment on the switch port where the phone plugs in and that cut the tcp link. So we switched it back. Having marked as no tagging and no vlan is how our vendor sets up all his clients, so i am curious how this will pan out.
