RE: T46G - Voice VLAN - 3cx - HP 4500G switch
Update: I have found that if I configure the port speed of the 4500G switch, or change the duplex, the phone will start responding (using the older firmware on the default VLAN), but the phone still won't respond on the correct VLAN. I changed the speed and duplex in the phone to 100-full, and set the switch to 100-full, however The T46G still doesn't reply on boot. On the switch, if I change the port speed or duplex once the T46G has booted, it will start to respond.

Perhaps there's an auto-negotiation issue on the port speed or duplex with Yealink Gigabit phones and certain switches? It's strange that it will start responding once I manually configure the switch port with a hard-coded duplex and speed (regardless of the phones duplex and speed setting).

Upgrading the firmware on the T46G to 28.71.0.224 seems to help with the port auto-negotiation issues. However, I still have the problem with the phone not wanting to work on vlan 122. Now the phone is just not joining vlan 122 at all. It's getting an IP on the default vlan and not ever switching to vlan 122. I've set the vlan both in the phone config and DHCP option.
