[cisco-voip] Dry Closure Phones

[David Zhars]

Yes apparently in the Dispatch center, the phones and radio traffic is
recorded.  Apparently (that word again) the PC needs a "dry closure
connection" so the user won't hear both phone and radio at the same time.
This may not be doable with what I am seeing, although the TAM stuff might
be a possibility.  I know the older analog phones definitely had this dry
closure stuff.  I will keep exploring!  Thanks everyone for the feedback.
