Be carefull with vlan assumptions. If two or more vlans exist across
multiple switches, how do you know if another vlan hasn't consumed all
available resources leaving little (or none) for your phone vlan?

Hint: look for "discarded packets in or out" on the physical ports of 
those switches in the path.
