Summary: dialog module causes OpenSER to stop processing requests

Initial Comment:
OpenSER sends a packet with a Record-Route as follows:
Record-Route: <sip:10.15.202.10:6080;lr;ftag=8621dc6d6281aa64o0;nat=yes;did=a16.4d576bc3>.

The other end sends a Record-Route as follows:
Record-Route: <sip:10.15.202.10:6080;lr;ftag=8621dc6d6281aa64o0;nat=yes;did=a16.4d576bc3>,<0 ap..

Upon receiving that packet, I see the following lines in the log file and OpenSER fails to respond to future requests until restarted:

Jan  3 09:13:56 p1 oser[18407]: ERROR:core:parse_nameaddr: no > found

More or less, here it's a logical problem. What to do with the dialog if
the update from the callee side failed (and having a dialog only with
caller related info)? Should the dialog be destroyed as incomplete ? or it
should be kept and change the code to accept dialogs wit no callee info.

Regards,
Bogdan

That was the entire RR. I'm guessing that's the parsing problem.

The entire INVITE I send is thus: (ip/domain changed)

The OK that they eventually send in return is:

Obviously the BRSIP device has a problem with sending malformed
packets.... but I think we can agree that OpenSER should just tell the
remote end..... ummmm..... "have a nice day"

Hi,

please post the complete RR header (multi body) returned in the reply. It
looks like openser reports some syntax error on this RR hdr.

Thanks and regards,
Bogdan
