I'm running into a problem with VoIP phones not working properly when the port they are connected to is configured with "ip verify source port-security". It appears the phone boots and gets an IP address, but beyond that it just hangs. I do not have DHCP snooping enabled for the voice vlan, but enabling it doesn't seem to make any difference. (No IP binding shows up even when DHCP snooping is enabled on the voice vlan.) The switch in question is a 3750 running 12.2(44)SE2. Is there any way I can make this work short of turning off IP source guard?
