Hi Kurtis,
Do you use any routeid in the rule definitions ? maybe that's the
looping cause.....Be sure it is set to NULL.

Thanks so much Bogdan, that line is super helpful.
I can't yet figure out why it's looping though. Here's what the log
now shows:

This seems to indicate an issue with my routing logic. However, I
can't see where I'm infinitely recursing. Here's the dialplan:
route{
script_trace( 1, "$rm from $si, ruri=$ru", "me");
if (!mf_process_maxfwd_header("70")) {
sl_send_reply("483","Too Many Hops");
exit;
}
#kurtis
if (is_method("INVITE")) {
setflag(1); # do accounting
route(4); # Call our dynamic route.
}
if (has_totag()) {
... (default from here)
and my custom route 4, which i've tried to poke at to remove the
recursion, but failed.
route[4] {
if (!do_routing("0")) {
send_reply("503", "No Rules matching the URI");
}
exit;
# route(relay);
}
Any guidance? I can't see how I'm causing it to recurse, but I've done
this in opensips before so I'm not surprised.
Thanks for all of your help!

Hi Kurtis,
On a first look, it seems your script doing doing a kind of
looping (maybe a recursive call of a route or so) - at least this
is what the log errors tell.
You can try the script_trace() function to understand how your
script is executed:

Hello mailing list,
I've been working on setting up OpenSIPS on an EC2 instance,
routing traffic between nexmo and our gateway, a FS instance on a
public IP. I was kindly directed to an earlier thread on OpenSIPs
and EC2
(http://lists.opensips.org/pipermail/users/2010-April/012393.html) but
have come to an issue I think is unrelated.
Here's the current architecture:
Nexmo -> EC2 NAT -> OpenSIPs -> EC2 NAT -> FS
I started with a walkthrough on the website
(http://www.unixnews.net/2010/09/dynamic-routing-with-opensips.html)
which roughly seems to be working. I've configured the gateway,
the routes, and so on. When I call my Nexmo number, it
successfully routes to FS and rings but, when answered, never
connects, failing after 30 seconds. This is, as expected, the OK
never reaching Nexmo and the RTP negotiation never starting. I
started poking around in wireshark and ran into another issue:
OpenSIPs is forwarding 9 invites in rapid succession (less than a
second) rather than just the one it received! FS *seems* to
handle this correctly (482 Request Merged) but it makes the SIP
trace an enormous mess and completely unreadable.
The opensips log is a mess, but isn't particularly useful:

Does anyone have any idea what would cause OpenSIPs to forward an
invite 9 times in less than a second? Fixing that should allow me
to move onto figuring out why it's not forwarding the 200 OK back
to Nexmo.
Thanks!
