[TrunkCom] historical EDACS question

[Jeff Kenyon]

Well, they did really well, with buying the other shops, and providing
ProVoice as an option to users.  Does anyone know if they will expand, and
if EDACS owners are encouraged to upgrade to OpenSky?  I know that some
people who start out with M/Acomm like Oakland County who has had Motorola
and maybe some GE conventional stuff over the years is going straight to
OpenSky, (that is if it ever happens as they have had many coverage
issues).
