Hey John, No they didn't had to do this because the audio path wasn't getting converted. On the legacy PBX, the audio path was still analog, but signalling from the phone to the PBX was digital (Key systems).
With VoIP, the ATA or PBX has to convert the analog audio signal into digital signal and this is where most of the issues are occurring.
