Re: Tips for good voice quality over frame-relay.

There are some rule of thumb that must be followed in-order to get a good voice quality over frame-relay.

1.Must fragment Data at low speed bandwidth regardless of whether they are on separate PVC.

2.The tc value must be set to a very small value to reduce token wait delay. Typically less than 10ms for both data and voice pvc.

3.Over subscription of bandwidht should be avoided in all cases. calculate the amount of bandwidth need for one call and dive the badwidth with the result

(either compressed or uncompressed) and assign a mxa-conn under the dial-peer vofr.

4. You must traffic shape voice calls from the high speed interface to low speed interface to the same value so that the low speed interfaces does not become

overwelmed with the traffic from high speed which will cause drop and will deifnately affect voice quality.

5. reserver the right amount of voice bandwidht for the aticipated number of calls
