The problem was in the function pjsip_rx_data_clone (inmultipart_data_clone). Thanks to people at metaswitch . . . "I've got a fix for the issue now - a list in pjsip wasn't being correctly initialized, meaning that when 'pj_list_push_back(&dst->part_head, dst_part);' was called in sip_multipart.c (204) it hit a null pointer exception (see https://github.com/Metaswitch/pjsip-upstream/pull/13)." pjsip_rx_data_clone was added end 2012, is now part of pjsip API: https://trac.pjsip.org/repos/ticket/1590 Problem solved! On to next problem! :-) James. -- <http://www.linkedin.com/company/76647?trk=fc_badge> openmindnetworks.com -------------- next part -------------- An HTML attachment was scrubbed...
