so I guess I can conclude based on the users replies so far is that I can
only see the TAG /Id from the mirrored port method and not from the pc
itself that has the VOIP software on it.
thanks

First, you had to have spanned/mirrored the trunk port. If that's the case,
then you can look right after the type/length field for the appropriate
headers. IEEE 802.1q and Cisco's ISL have different tags but they will show
up.
