I cannot find a configuration example of Qos for a SIP trunk. I can see where I can do some things with sip but it is the RTP traffic that I cannot seem to find a way to get it prioritized. I have version 8.0(3).
Now I have the CCM terminating the trunk going to the ASA, then a router over 2 t1s to an ISP that dumps it to the PSTN.

Richard,
You have to configure the policy for the QoS on the ASA. Firstly are you marking the RTP traffic anywhere in your network - as this would make things much easier, DSCP values? If not - what port range are you using for RTP, as you can configure a policy based on this port range? If you don't know - you can use a source/destination acl to identify the RTP traffic? If you have VPN tunnels - you can use these?
something like:-
access-list inside_QoS line 1 extended permit ip x.x.x.x y.y.y.y z.z.z.z w.w.w.w
class-map inside-QoS-example
match access-list inside_QoS
policy-map Inside_QoS_policy
class inside-QoS-example
police input 8000 1500 conform-action transmit exceed-action drop
service-policy Inside_QoS_policy interface inside
HTH.
