automatic test coverage for emergency call support on osmo-bsc
Emergency calls can be enabled/disabled on a per-BTS level. In OsmoMSC, you can configure the number to which emergency calls should be routed to.
They should be working, but I have the feeling it's one of those features that are rarely used in our existing user base, and we have zero automatic test coverage. Let's change that
- BSC_Tests.ttcn test handling CHAN RQD (BSC expeted to reject if "allow-emergency deny"; channel activation otherwise)
- BSC_Tests.ttcn test handling EMERGENCY SETUP (BSC expected to reject if "allow-emergency deny", pass to A otherwise)
- BTS_Tests.ttcn test sending RACH request for EMERGENCY
