I'm a little confused on how this works, I'm hoping someone can clarify it for me.  On our network we have VOIP service on VLAN 200, Data on VLAN 300.  Our switchports I believe are defined as access ports, which means they should only have 1 VLAN (I don't know what the VLAN is on the access port - I assume 200 or 300).  But the telephone plugs directly into the switchport then the computer plugs into the PC port on the back of the phone.  How is it that this works?  It seems to my befuddled brain that this means there are 2 seperate VLAN's sending info on the switchport - the phone over 200 the PC over 300.
