Hi

The softphone will not use the voice VLAN, so whilst you would normally have a standard/consistent edge port config which would likely include a voice VLAN, you don't NEED it as such.

You would however want to consider your configuration for QoS; if you are using trust-cos or trust-ciscophone then you will want to either switch to trust dscp, or (better) a policed input service policy. If you're not sure how to do it, using auto qos trust cisco-softphone will configure a service policy that will work well for both IP Phones and softphones.
