But why isn't SOT paged for incidents, net call and other info that relate to them only, not medSTAR?
You tend to make the assumption that the Pages that you see on the paging scanner sites are ALL paging traffic that is sent out. That is not the case.
In my line of work, we can be turned out in numerous ways, some the public are aware of, others not. R/T, Station Bells, T/P, MDT, Phone, Pager, Crash turnout system...
Things happen that you don't need to be aware of.
Get over it.
