Computer with 10.200.x.x on vlan3 connected through VOIP phone on 10.98.x.x on vlan 7 would this work?

Hello EE,
We have a switch with phones connect to it on 10.98.x.x vlan 7 and a switch of PCs on 10.200.x.x on vlan 3.  Is it possible to save room on switch ports to connect the PC into the phone or is there an issues with the IP/VLAN differences?  I am not sure on connectivity through the phone so am not sure the limitations.

you can though the phone network port might be 100MB. the feed to the phone might be 100MB also.
if properly configured, the switch will assign/group ip phones into VLAN7 while the PC will be on Vlan3 IP Assignment is done by the Cisco Router.

The connection/phone qos will prioritize traffic for voice versus computer data.

our phones use PoE ? Switch?

Assuming you have a Cisco Switch you will be pleased to know that it is as easy as putting the phone in the phone vlan and the computer on the computer vlan on the switch interface.  Cisco has made it so on a given interface you can have two vlans IF one of those vlans is a voice vlan.

So the config would look like:

interface Fa0/1
switchport voice vlan 7
switchport access vlan 3

Then its just a matter of power and QoS if you have issues with the data traffic interrupting the phone traffic.
