No, this is incorrect. a re-INVITE is sent once and then re-sent at the
500ms..1s..2s..4s points. If sems gets a 100 Trying back however, it
stops the retransmissions.

I have just checked your lb.log and looks like the re-INVITE was not
resent. Which leaves me wondering why it doesn't work for you like this.
Works on my test VM - there is a trace below. Could you send me the
trace from your server (ngrep -s0 -t -Wbyline -d any SIP port 5080) and
sems.log, after doing sems-stats -c "set_loglevel 3", so if this is a
sems problem we can report it to sems developers. Thanks.
