hello ,
my name is Michael
last week i configured qos on cisco 887va in our small company but i still have packets drop :delay , Dropped calls.
i have 15 ip phones that work with codec g729 and blf Features. the Bandwidth for each 1 call is around 55-60kb
the total internet Bandwidth is 40Mpbs-down and 3 Mpbs up.
i hope that someone can help me with this.
this is the policy-map and the configuration:
Service-policy output: Voip
