Hi all
OpenSIPs seems to be sending a 491 Request Pending when a lot of RE-INVITES are received. I found out the following threads regarding this problem: http://opensips.org/pipermail/users/2010-May/012724.html http://www.mentby.com/Group/opensips-users/re-invite-problem-gt-491-request-pending.html So, it seems that I could get rid of that error by adding a t_newtran() before t_relay() when I handle an ACK: http://www.opensips.org/html/docs/modules/1.6.2/tm.html#id294024 Like this: * if ( is_method("ACK") ) {* * if ( t_check_trans() ) {* * # non loose-route, but stateful ACK; must be an ACK after a 487 or e.g. 404 from upstream server* * t_newtran();* * t_relay();* * exit;* * } else {* * # ACK without matching transaction ... ignore and discard.\n");* * xlog("L_WARN", "[$mi] discarding ACK\n");* * exit;* * };* * };* But I'm not sure if this is correct. I'd appreciate any comments to see if I missed something before testing live.
