Demo of preferential calls in the #DMR #trunking system (Hytera calls these priority group).

Start: both radios subscribed to the parrot TG, Parrot is medium prio in the call priorities on radio 1.

I request TG 91 via DGNA on radio 1 (I have to do this is because it's not programmed in the same scan list as parrot on my radio).

TG 91 becomes active and I listen it. Then I initiate a call to Parrot on radio 2, and radio 1 now switches to this preferential call.

The preferential call (priority call) functionality needs to be enabled in the #trunking controller for this to work (screenshot of option attached).

I don't keep it enabled on my repeater usually because it's annoying (the announcement replaces one voice frame in the payload channel).

But I hope someone might find this useful.

As a reminder, the whole trunking base station stack is open source, so anything can be implemented (within reason).

Also forgot to add, the original call being replaced remains active on the BTS, so I can switch back to it once the higher priority call I was drawn into has finished.
