I'm about to run our first site using voip through our ISP's mpls network. I was going to mark the traffic outbound, but I want to guarantee that the phones get a minimum amount of bandwidth when needed. I'm not sure if priority is a good choice since it polices the traffic also, so is using the priority command better than the bandwidth command under a policy map for voip?
Also, should I mark the traffic outbound on the serial interface with the EF tag, or should I mark it inbound on the lan side of the router?
You need to make sure that your ISP runs the QoS policies throughout their whole network till the egress PE after which the packets will be handed over to your remote end (CE) location. (thts the default case with most of the ISPs)
You need to apply the service policy command outbound on the serial interface.
Make sure you have similar configs at the remote end router as well so that you have policies applied on both the sides.
