Does the IP Phone and the PC use the same ip address or different one? Thx!

Stuck in a never ending cycle of file copying. RE: Avaya IP Phone PC port icet500 (Vendor) 8 Jun 20 09:55 It depends on the switch port configuration which your Phone is plugged to. If you have no vlans configured on your switch then the pc and the phone will take an ip from the same range of your dhcp. If you have data and voice vlans then the phone will take an IP from the voice and your pc from the data vlan.
