San Antonio, Texas, and the State of Florida are using or are in the process of building ProVoice EDACS systems with ESK. Cecil County, Maryland utilizes a VHF ProVoice system which does not use ESK, but uses a variant of EDACS that cannot be followed by a consumer scanner, even if it has analog talkgroups.
EDACS ProVoice systems use the MA/Com EDACS control channel.
AEGIS was a predecessor of ProVoice on EDACS Systems.
