[asterisk-users] New thread - SIP over VPN

[Frank Bulk]

Resending is not a waste if the re-transmitted packet can arrive within the
jitter buffer window.  Practically speaking, though, since UDP packets are
generally not retransmitted (unless it's within some kind of TCP-based
tunnel), it's a moot point.

Re-sending audio packets is waste of resource,
Better to have an audio-stream with an occasional missing packet, than
the delay of waiting for re-transmission and re-ordering.
