The outgoing (relayed) e2e ACK is not captured by the sipcapture module in "transaction" capture mode (the default), because of tm module internals.
You have to explicitly capture it in the onsend_route.

onsend_route {
    if ($rm == 'ACK') {
        sip_trace();
    }
}

Cheers,

Federico

It's true; the closest and comparably terse adverb I can readily conjure
is "surreptitiously", which implies a more actively deliberate and
nefarious level of packet forwarding.
