Question : Problem: Connecting 3com switch to existing network

hi
i have a situation where i have to set up and configure 3com switch (4500 series, 50 port PoE).
i m connecting this switch in a room that has an existing network port(currently one avaya ip phone connected to it and a pc thru the ip phone).

I need this switch to be able to allow both voice and data. once i hook up this switch to the port
the data is working fine, but not voice.

so i need help configuring the ports on this switch.
the existing network structure is vlan 1= data and vlan 2=voice.

how should the individual ports be configured and how should the uplink port be configured.

thank you

usualy you have to set up a trunk between the 2 switchports of the 2 switches.
Only then your vlan traffic will go over the trunk.  Than you can put  individual ports a vlan
