Hi guys and girls!
I wish to prioritise VOIP traffic generated from our internal network and directed out our ADSL 256/512Kb line.
I got a shock last night when I applied the following QoS config to our company router. ALL the interfaces went "administratively down" when I applied the policy to the interface!! (using the service-policy command on interface Dialer2)
Would someone mind suggesting what fatal error I am making?! ;-)
Note that when VOIP traffic is not queued, I wish to utilise the full capacity of the ADSL line, rather than have 56Kb of bandwidth reserved purely for VOIP.
Your comments are much appreciated. See config below.
Best wishes Paul
