Hello,
From the output of dlg_list, I can see that the ACK was never received
by OpenSIPS, so seems this is the source of your problem.
You could try to set the dialog timeout to a lower value after the 200
OK is received ( couple of seconds ), and increase it after the ACK is
received to a couple of hours.

I've run into an issue where /very/ rarely, dialogs will "hang", that
is, the dialog will continue to exist even though the call never
connected. In the example I managed to track down, the proxy should
reject the call (because a limit of concurrent calls has been reached)
and at first, it seems like it's going to... but then it sends a 100
Trying and continues to route the call to the destination. From there,
everything spirals and the dialog doesn't die until it hits the global
timeout.
The relevant portion of my script looks like:
# Check gateway calls total
if ($avp(custgwtotal_limit) != "0" && $avp(custgwtotal_limit) != NULL
&& $avp(custgwtotal_limit) != "")
{
get_profile_size("custgwtotal","$rd","$avp(custgwtotal_count)");
if (!$avp(custgwtotal_count) < $avp(custgwtotal_limit))
{
sl_send_reply("486","Endpoint Session Limit");
exit;
}
}
set_dlg_profile("custgwtotal","$rd"); #count total calls to customer's IP
I've attached a pcap example of what the signaling looks like when the
dialog hangs. For this example, the output in dlg_list looks like:

Any help would be appreciated.
