VoFR PVC for data and PVC for voice with FRTS

Dear friends, It is my first experience configuring VoFR. My access rate is 128 Kbps and the CIR is 64 Kbps. I configured the router following some cisco examples using "vofr cisco" and FRTS into my "map-class" for voice. You can see my config in the attach file.

It works fine, the quality voice is good (2 calls)when the link is congested up to 100% through bi-directional ftp download.

However, I cannot get a speed upper to 64 Kbps. I understand that it is as FRTS works and it is necesary to QoS for voice. But I`m paying to my service provider a price for 128/64 and I never won`t get a speed greater than 64 Kbps.

How can I solve this problem without increase my CIR?. It has a additional cost.

I`m reading that some solution could be create two PVCs: one for voice and one for data. How should I configure them to get a burst traffic for data upper to 64 Kbps without affect my quality of voice?

Thank you for your suggestions.

Edwin.

The following document has some explaination on the queueing on frame relay interfaces. This might help you understand how to configure different pvcs for voice and data and utilise the given cir fully.
