Re: Asterisk ignoring replayed libpcap sessions

Yes, that's true, but is it only SIP that you are talking about ? And
even in that case... it's not so simple.

TCPReplay also replays UDP packets, but if for instance those packets
contain nonces, identifiers that can be changed from either side, or
other elements of freshness, you can't expect that a server will react
correctly to a blind REPLAY of a former session... much in the same way
this wouldn't fly with TCP based protocols
