We are planning to use VOIP in our office. Since the new voip phones will use the same network, i would like to somehow separate the voice packets and the data packets. I'm thinking subnetting or VLAN. And i'm not sure at all how subnetting will work, or how to configure things in that manner. I do have an idea bout VLAN's, and I know our switch supports. Other big reason I wanna do this is because of collision. If a collision occurs between computers on the network that should not affect the voip phones and vise versa. My question is how can i do this, or what is the best solution? Any help will be much appreciated. Thanks.

The main difference between doing different subnet and VLAN is the separation of the broadcast domains not necessarily the collision domains. Remember that in a switch each port is it's own collision domain. If you subnet phones from PC's you will create a flat network with to different networks, however broadcast traffic would still be seen across the network. If you set up a VLAN you are logically separating the broadcast domains and only traffic belonging to a port's specific VLAN will be seen. Most recommendations call for setting up a VLAN for voice. If you have multiple switches or devices that need access multiple VLAN's you will have to set up trunking.
