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.
