Hello,
What is the OpenSIPS SVN version and revision that you are using ?
There was recently a bug found, where dialogs would get stuck for
Cancels that had a To-Tag, and it was fixed in rev 9382 .
Regards,
Vlad

Hey All,
I'm doing simple dialog based topo hiding and I noticed that CANCELd
dialogs are hanging around in state 5. They are starting to stack up.
Here's an example of one of the dialogs.. I kind of thought that when
the timeout ran down, the dialog would disappear, but it's not:
dialog:: hash=1645:1160860947
state:: 5
user_flags:: 0
timestart:: 0
timeout:: 0
callid:: [email protected]
<mailto:[email protected]>
from_uri:: sip:[email protected]:5060
<http://sip:[email protected]:5060>
to_uri:: sip:[email protected] <mailto:sip%[email protected]>
caller_tag:: 201142122000875167015
caller_contact:: sip:1.2.3.4:5060;transport=udp
callee_cseq:: 0
caller_route_set::
caller_bind_addr:: udp:5.6.7.8:5060 <http://5.6.7.8:5060>
callee_tag:: 2011411220122012615936129
callee_contact:: sip:9.8.7.6:5060;transport=udp
caller_cseq:: 1
This has been around for about 18 hours! SIP Trace looks pretty normal
really.
To properly support topo hiding, I've got this at the top of the route
processing:
if (has_totag()) {
if(is_method("INVITE|ACK|BYE|UPDATE|CANCEL")) {
if(match_dialog()) {
t_relay();
exit;
}
}
I originally didn't include CANCEL in the method check, but it caused
CANCELs to be ignored by one of the endpoints. Granted, I know the
endpoints are using switches that arn't known for being very
compliant. When I added in CANCEL in this check, the sip traces now
look proper and both sides are happy with the request being
terminated, but the dialog persists in memory.
Any ideas why these dialogs are not clearing out of opensips?
Thanks,
Brett
