Hi
Cisco has fixed the problem. You should be getting emails on your cisco
account now.
Regd. your question -
Why not use shaping ?
If I remember correctly from DQOS (deploying QOS on enterprise n/w) class,
- ingress side set ip prec 5 for all voice traffic
(on dial peer voip - set ip prec 5)
- egress side define
class-map c1
match ip prec 5
policy-map p1
class c1
shape 40
Shaping will take place even when there is no congestion
thanks
