/* * In this module we handle the scenarios of themwi-mncc and/or themwi-mgw * shutting down while we are connected to them. In both scenarios we * terminate all active calls (graceful disconnect signaling toward SIP * callers and toward whichever ThemWi daemon is still running, if either), * but our themwi-sip-in process itself stays running. This way once * the other required processes restart, inbound calls will start working * once again, without needing to restart themwi-sip-in. */ #include <sys/types.h> #include <sys/socket.h> #include <sys/time.h> #include <netinet/in.h> #include <stdio.h> #include <stdint.h> #include <stdlib.h> #include <string.h> #include <strings.h> #include <syslog.h> #include "../include/mncc.h" #include "../include/gsm48_const.h" #include "call.h" extern struct call *call_list; static struct gsm_mncc_cause shutdown_cause = { .coding = GSM48_CAUSE_CODING_GSM, .location = GSM48_CAUSE_LOC_PRN_S_LU, .value = GSM48_CC_CAUSE_NETWORK_OOO, }; void shutdown_gsm_conn() { struct call *call; for (call = call_list; call; call = call->next) { call->mncc_state = MNCC_STATE_NO_EXIST; if (call->overall_state != OVERALL_STATE_DEAD_SIP) { call->overall_state = OVERALL_STATE_TEARDOWN; disconnect_tmgw(call); disconnect_sip(call, &shutdown_cause); transition_dead_sip(call); } } } void shutdown_mgw_conn() { struct call *call; for (call = call_list; call; call = call->next) { call->mgw_state = MGW_STATE_NO_EXIST; call->mgw_xact = 0; if (call->overall_state != OVERALL_STATE_DEAD_SIP) { call->overall_state = OVERALL_STATE_TEARDOWN; disconnect_mncc(call, GSM48_CAUSE_LOC_PRN_S_LU, GSM48_CC_CAUSE_NETWORK_OOO); disconnect_sip(call, &shutdown_cause); transition_dead_sip(call); } } }
