When I have a computer directly connected to the Cable Modem I get 9.84MB Down and 1MB Up. When I put it behind the ASA 5505 with policing on the interface, I only get 4MB Down and 660Kb Down.
What I'm wanting to do is setup this up to enable my VoIP to have a higher priority and shave 128kon both the Up/Down for the VoIP traffic. I also want to make sure I don't exceed the inbound and outbound thresholds.
Any ideas?
I''m using a 5505 Security Plus

Hello,
On the access list that you have for policing, deny the Voice protocol as well as the RTP ports used by your voice over IP infraestructure, that will enable you to not be policed. Additional, you can create a new access list with permits in order to give priority to these traffic.
Let me know.

Is this what your suggesting?
access-list voip extended permit udp any host 208.64.8.6 range sip 5061
access-list voip extended permit udp any host 208.64.8.6 range 16384 16538
!
class-map Voice
match access-list voip
class-map inspection_default
match default-inspection-traffic

Was able to fix most of this issue. It ended up being a duplex mis-match with the cable modem. I had to get the cable provider to hard code it.
