QoS

I have two 3661 conected via a T1 satellite link over Frame Relay. Could someone tell me what QoS parameters should one enable in order to get the highest possible voice quality.

I'm using G729 codec at 8kps with RTP and RTcP comression, which is enabling me to run voice over a 12kbps channel.

Do I need to enable LFI?

Should one consider DiffServ?

How about different queueing techniques?

Should I consider WRR, WRED, CAR and/or other QoS

features?

Thank you in advance.
