By default, asterisk should forward RTP packets without any buffer, without reordering or doing anything. Today Asterisk renumbers packets - thus hiding packet loss and reordering. This is bad.

Forwarding with packet loss and reordering is quite ok as default. The endpoint in the call will sort it up with a jitter buffer.

In some cases Asterisk is the endpoint of the RTP stream (IVR, protocol conversion). In that case we can apply a buffer like any endpoint. But not by default.

I guess cases with transcoding involved also requires a jitter buffer.
