I have a two remote sites each running call manager express with one site having only a 4MG ADSL connection to the internet therefore leaving only 512k for upstream traffic. There is also a vpn tunnel between the two sites.
Users are experiencing qos issues when making intersite calls jitter packet drops etc.
At the moment there is no qos deployed so i have come up with the following recommendation to prioritize the voice traffic.
class-map match-all Voice
match ip dscp ef
class-map match-any Call_Signalling
match ip dscp cs3
match ip dscp af31
priority percent 20
bandwidth percent 5
interface fastethernet 0/1
service-policy output WAN-EDGE
I would like to know if there is any other mechanism i can use and if the above recommendation will be sufficient to resolve the qos issues on this link...thanks.
