<div>Couple of comments:</div>
<div>To turn on debug, set:</div>
<div>debug=3 (or higher) </div>
<div>in opensips.cfg, then restart (opensipsctl restart)</div>
<div><br></div>
<div>instead of using tcpdump, try using a tool like ngrep or tshark:</div>
<div>ngrep -qW byline port 5060</div>
<div>tshark -i any port 5060</div>
<div><br></div>
<div>It's hard to diagnose the problem you are having without more information.
I guess what you need to check on:</div>
<div>1. Is opensips listening on the same interface you are receiving the
message? (netstat -nlp)</div>
<div>2. Is there a firewall blocking the traffic?</div>
<div>3. Is opensips actually running (seriously!)</div>
<div>4. Does your opensips.cfg actually handle REGISTERs? if you have a bunch of
if (is_method("INVITE")) but nothing for REGISTER, it might end up just ignoring
it altogether.</div>
<div><br></div>
<div>normal "debugging" for the transactions isn't something you need to set
during compile, it's a configuration parameter.</div>
<div><br></div>
<div>Ultimately, that should help out. The opensips debug log will point you in
the right direction, but honestly, I think while learning opensips, that debug
log might be a little intimidating for this sort of problem. I'd check the other
points first. :)<br><br></div>
