Here is my situation. I have four remote offices, one connected by aIt really depends where your bandwidth is getting used up.
wireless link, one connected by a regular T1 and two connected by frame.
We have just switched PBX's and are now using VoIP phones instead of
landlines. My problem is (obviously) with VoIP, the voice is getting
choppy whenever there is high data transfers.
My question is, for the office with a T1, should I put a QoS box on both ends? (One here at HQ, and one there?) Same with the frame? And correct me if I'm wrong, but I will need one at both ends for the wireless link.
QoS and traffic shaping works (best and easiest) on outbound traffic only, so if you can determine which links are being flooded with (non VoIP) data transfers, and then put a QoS box on the end sending the data, it may solve all the problems.
If all the links are being flooded, then chances are you will need shaping at each end - 5 QoS boxes.
Keep in mind, if you are using linux machines as any existing gateway/routers, then you can probabaly just install the tc tools and do the shaping on them, in their existing place in the network.
