[TrunkCom] phone patch and I-calls

[Jeff Kenyon]

ight, and I am surprised at the number of users who get this access.  On
our system in Grosse Pointe we were trained to do I-calls or in our case
private calls, but after a lengthy discussion we decided that it would b
best to not let anyone have that ability since people would just be
talking from person to person, and if we had phone patch capabilities i
doubt that they would be given out as freely on our system as they are on
others, and the Motorola rep who I knew who no longer is with the company
actually discourages that the private call and phone patch calls be given
to everyone because of over useage, but with a trunked system you always
have that paper trail.
