Cisco unified connections subnetting I need some clarification when using Cisco unified connections as a basis for my VoIP network. If I have a PC connecting through an IP phone, how can I put the PC into a separate subnet? If the IP phone and PC are separate subnets, how would they be able to communicate?

as shown in the figure , the layer 2 switch will be connected to the ip phone with connection called **_mini trunk_** which acting as a trunk carry two Vlan's the data one and the voice one . on the ip phone itself there is mini switch which will untag the voice vlan and use it for voice traffic and untag the data vlan and forward it to the pc port . voice traffic is treated this way mainly for one reason that is QOS ,where voice traffic need to be prioritized than the data traffic
