<html><head><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /></head><body><div>I am trying to implement a simple topology hiding B2BUA with opensips 1.11.5<br /><br />most things work except that re invites for session expiry are being ignored.<br /><br />I assume that I am missing something in my config.<br /><br />the strange thing is that I see no debug to syslog when the Invites come in even with debug set to 9.<br /><br />the basic config is a client on port 5061 (C) inviting the B2BUA on port 5066(B) with then invites the main server on another host on port 5060(A).<br />I do not expect and inbount calls from A<br /><br />C invites B, B invites A all proceeds normally until after 15 minutes A invites B and is ignored then sends bye a number of times.<br />none of the reinvites or byes are reported in the logs.<br /><br />C then hangs up sending a bye to B, B sends a bye to A and gets 481 Unknown Dialog.<br /><br />below is my config<br /><br />route{<br /> if ( !mf_process_maxfwd_header("10") )<br /> {<br /> sl_send_reply("483","To Many Hops");<br /> drop();<br /> };<br /><br /> if (is_method("OPTIONS"))<br /> {<br /> #xlog("L_NOTICE", "$ci|end|unsupported method");<br /> sl_send_reply("404", "Not found");<br /> exit;<br /> }<br /><br /> if(is_method("INVITE")){<br /> xlog("L_NOTICE","got invite");<br /> if($sp=="5061"){<br /> xlog("L_NOTICE","got invite 5061");<br /> xlog("L_NOTICE","[$mi] before B2B request\n");<br /> $ru="sip:"+$tU+"@172.22.2.140:5060";<br /> b2b_init_request("top hiding");<br /> xlog("L_INFO","[$mi] after B2B request\n");<br /> }else{<br /> xlog("L_NOTICE","got invite $sp");<br /> xlog("L_INFO","[$mi] not from 5061\n");<br /> }<br /> exit;<br /> }else{<br /> xlog("L_ERR","got request method $rm
