Hi, I noticed that my publishc callback was not called when authentication eventually fails. In publishc.c I found the following: 486 // Callback should have been called. 487 // Calling it here will crash the system since pubc might have been 488 // destroyed 489 // 490 //if (status != PJ_SUCCESS) { 491 // call_callback(pubc, status, tsx->status_code, 492 // &rdata->msg_info.msg->line.status.reason, 493 // rdata, -1); 494 //} Is this still accurate? As far as I can see the _delete_flag should guard against this sort of thing. Ruud Klaver AG Projects
