We are looking to start offering phone service off of our gateways, and are running into some issues with applying QoS tags on inbound traffic to the C5. We are tagging the outbound traffic at our gateway, and I have verified via packet capture that it is being set correctly.
I have tried creating an access list in the A5 to tag the inbound traffic, but a packet capture from the gateway shows that it is not applying the tag. I have also confirmed with Mimosa support that the ACL is configured properly.
For those of you already offering VOIP service, are you utilizing QoS, and if so do you have any insight here? Any other useful tips?
