[SR-Users] siptrace loosing an ACK

Hello,

indeed the outgoing ACK was not captured. I did a commit in the last 
days that should address this issue:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=9d8df2527d13878cee23af5b14f142a0cc4cd878

You have to use the onsend_route block for it, like:

onsend_route {
    if(method==ACK") sip_trace();
}

If you can test the master branch for this case and report that all 
works ok, then I can backport to fix it on the stable branch.

Cheers,
Daniel
