I have a remote site connecting to a secondary site using a GRE tunnel. The remote site has a second GRE tunnel to the main office. The remote site and secondary site are connected to allow VoIP traffic. I am having intermittent bandwidth issues resulting in dropped calls at the remote site.
Where would a QoS policy normally be located? Should it be placed outbound on the physical interface fa0/1? If the QoS policy is placed on fa0/1 how will it know what traffic is inside the VPN encrypted data? I need to prioritize VoIP traffic to eliminate or drastically reduce dropped calls.
I have posted a copy of the router config with secure information removed.
