I am trying to implement a simple topology hiding B2BUA with opensips 1.11.5
most things work except that re invites for session expiry are being ignored.
I assume that I am missing something in my config.
the strange thing is that I see no debug to syslog when the Invites come in
even with debug set to 9.
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).
I do not expect and inbount calls from A
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.
none of the reinvites or byes are reported in the logs.
C then hangs up sending a bye to B, B sends a bye to A and gets 481 Unknown
Dialog.
below is my config
route{
if ( !mf_process_maxfwd_header("10") )
{
sl_send_reply("483","To Many Hops");
drop();
};
if (is_method("OPTIONS"))
{
#xlog("L_NOTICE", "$ci|end|unsupported method");
sl_send_reply("404", "Not found");
exit;
}
if(is_method("INVITE")){
xlog("L_NOTICE","got invite");
if($sp=="5061"){
xlog("L_NOTICE","got invite 5061");
xlog("L_NOTICE","[$mi] before B2B request\n");
$ru="sip:"+$tU+"@172.22.2.140:5060";
b2b_init_request("top hiding");
xlog("L_INFO","[$mi] after B2B request\n");
}else{
xlog("L_NOTICE","got invite $sp");
xlog("L_INFO","[$mi] not from 5061\n");
}
exit;
}else{
xlog("L_ERR","got request method $rm from $si: $fU, $tU");
sl_send_reply("501", "Not Implemented");
exit;
}
}
