hi Vinod

by default, IP Phone`s interface that connect to upstream SW is working on native vlan mode, all of traffic (include voice from itself and date from PC) are untag. people in order to distinguish between voice and data, so using different vlan to transfer voice and date. here trunk is used. for example:

int f0/1

switchport access vlan 100 (for date)

switchport trunk native vlan 100

switchport voice vlan 200 (for voice)

switchport trunk enc dot1q (to direct IP Phone using trunk)

exclude 4000 6000 serial, they are using DTP to auto create trunk with IP Phone.

The Port have to be access port in order to carry the IP-Phones voice vlan & the Date Vlan.

I am attaching a document that can help you out.
