Khan,
Here is a link to a pretty nice document on SIP:
http://www.tm.uka.de/itm/uploads/folien/100/MMK-05-SIP-4up.pdf
Two very good tools for looking at SIP requests and replies are tshark
and ngrep. On the opensips proxy try running "ngrep -q -W byline port
5060" from the command line.
Just for the record, that rewritehostport to the asterisk server looks
pretty wrong. I imagine there are a multitude of other problems and I
don't think this problem is related to the symptoms you describe but
fixing it might be a good place to start.
rewritehostport should be of the form rewritehostport("1.2.3.4:5060");
where 1.2.3.4 is the IP and 5060 is the port that you want the request
URI to contain. Unless you do some type of over-ride this will also
be where the message gets sent, which is probably exactly what you
want to happen.
