The phones themselves won't pass tags through to the PC (untagged only).
So the short answer is that yes, if everything is supposed to be tagged, then that command would do it. but the longer answer is that if you did that, no traffic would ever get to your PC behind the phone. :) HTH, Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE-M #153, JNCIS-ER, CISSP, et al.

Packets with none dot1q header will be in the native vlan and assumed to be from the PC's, and packets with the dot1q header and vlan 170 tag will be in the 170 vlan. But what will happened if you get a task to tag all vlans travelling a trunk? Vlan dot1q tag native? -Ralph
