Hi, I think there is a bug in pjsua_acc_find_for_incoming(), in /* Check that there's at least one account configured */ PJ_ASSERT_RETURN(pjsua_var.acc_cnt!=0, pjsua_var.default_acc); This function is called in on_incoming_call() and options_on_rx_request(); So when I delete my accounts, someone calls me or the SIP proxy send me OPTIONS request, I get assertion fail !!!! I'm using microSIP, when I close my microSIP, I call PJDestroy() void CmicrosipDlg::PJDestroy() { PJAccountDelete(); pjsua_destroy(); } I think we should not call PJAccountDelete -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
