Hi, according to a recent commit in OpenSIPS dialog module it seems that it crashes when trying to match a dialog for a request with no From tag: http://opensips.svn.sourceforge.net/opensips/?rev=6595&view=rev I've checked the head version of the module in modules_k an the bug exists: http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip- router;a=blob;f=modules_k/dialog/dlg_hash.h;h=bd1de8717bbfec5fd76a461f251f2bdbc9f5754b;hb=HEAD I have to play a bit more with Git before commiting something so I'd ask if somebody can fix it :) -- Iñaki Baz Castillo <ibc(a)aliax.net>
