With Unitrunker v1, is there a means of audible alert when a specific type of traffic is intercepted. I'm monitoring a very busy EDACS system that has a few digitally encrypted talkgroups. I'm only interested in these, but they are rare and difficult to pick out on the busy calls interface. Besides, it would require me to stare incessently at the display for those rare occurrences. Aan alert would draw my attention to the display.
