ProVoice is MA/Com's (formerly Ericsson) implementation of IMBE digital modulation for radio communications. It is not APCO-25 compliant, but does use the same IMBE vocoder developed by DVSI Inc. The technical difference between ProVoice and the APCO Project-25 standard is how error correction and modulation is provided to transmit the data.
There is also an older type of digital communications for EDACS Systems, which goes by the trade name AEGIS.
El Paso and San Antonio, Texas, the State of Florida, and St Tammany Parish, Louisiana, are using ProVoice EDACS or are in the process of building ProVoice systems. Cecil County, Maryland utilizes a VHF Pro-Voice system with ESK.
EDACS ProVoice systems use the MA/Com EDACS control channel.
There is no scanner available today that can monitor EDACS ProVoice Digital voice.
