[OSL | CCIE_Voice] SRST Source interface

[kill mill]

Guys I wanted to know if we use VOice vlan to source the SRST would
they deduct any points in the lab as supposed to loopback . Technically
voice vlan will be up all the time on the BR router because of the phones so
if i got 0 in  SRST then its prolly because of something else correct ?
