Qos VoIP FR

[icabrera]

Whay type of QoS for VoIP can we use in a Frame Relay network? Actually, our customer has a FR connection only for data traffic and this connection has configured the "frame-relay payload-compression packet-by-packet" command. Now, we want to use this connection for the VoIP traffic too, but we don´t know if this compression can be used with VoIP packets.

You will need to use FRF12 with LLQ/CBWFQ.

This will support cRTP, but not data compression, at least it does not appear to. And you will need to use Cisco frame encapsulation to do cRTP, though they are working on IETF. Anybody have an update on this?
