2 * In this module we handle the scenarios of themwi-mncc and/or themwi-mgw
3 * shutting down while we are connected to them. In both scenarios we
4 * terminate all active calls (in the case of MNCC socket closing, only
5 * those calls that came on that socket), but our themwi-sip-out process
6 * itself stays running. This way once the other required processes restart,
7 * outbound calls will start working once again, without needing to restart
8 * themwi-sip-out.
