[TrunkCom] EDACS System Questions

I think that this could be some kind of data.  'I've noticed on an EDACS
system in my area that it will make that noise, but not consistently.  It
might be something that has to do with being on the fringes of a coverage
area. Sometimes too, if you listen in conventional mode you'll hear that
noise as well with no voie to fololow.
