[Serusers] www_challenge and transaction handling

Hi! I've some troubles with the radius authentication. If the radius authentication takes longer than 0.5 secondes, the client retransmits the message and causes another radius request. I tried to catch the retransmissions using t_newtran (ser.cfg snippet at the end of this email). This works fine for messages with credentials, but for the initial REGISTER messages (without credentials), which will be answered by www_challenge(), this causes the following warning: WARNING: script writer didn't release transaction Looks like www_challenge works only stateless. Is there a way to handle the challange stateful? Btw: I'm still using 0.8.12 - is this solved in newer versions? regards, klaus if ( !t_newtran()) { sl_reply_error(); xlog("L_ERR", "error creating new transaction\n"); break; }; xlog("L_INFO", "creating new transaction ... done\n"); if (!radius_www_authorize("")) { www_challenge("", "0"); break; }; if (!check_to()) { if (!t_reply("403", "Forbidden - please use proper To")) { sl_reply_error(); }; break; }; if(!save("location")) { if (!t_reply("500", "Error saving contact")) { sl_reply_error(); }; break; }; break;
