We are in the process of upgrading our bandwidth at our branch locations into 3 Mbps MPLS networ and we only run Citrix traffic and IP Voice (Interoffice calls) from our Branch locations into our HQ.
We expect Bandwith utilization to typically max out at 1.6 MBPS. Do you think we need to configure QoS for the voice traffic since the circuit will only be 40-50 percent utilized? My thinking was why should I configure QoS if the bandwidth is only at 40 - 50 percent. The voice traffic should have enough bandwidth to communicate over the wire.
Is my thinking correct or should I configure QoS across this MPLS network?
Re: VOIP over MPLS network with bandwidth util of 50%
You really do need your QoS. Two reasons:
(a) Your average 40-50 % contains peaks of near 100%, which may result in packet drops. On a compressed voice call, even 1% is enough to severely degrade quality.
(b) Your average will conceal peaks and troughs of traffic queues. At the peaks, average queue lengths will increase, creating jitter (variation in arrival time of voice packets). More than 50ms of jitter, and your voice session is trashed.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
