I am using A Pleiadis channel bank with VAD (voice answer detection). My carrier is complaning when they reach messages from cell phone stating “party you are calling is out of range”. They are being charged. Has any one used the answer suypervision timer on Pleiadis? Does it work. Any one has other sugestion? I hear they is other equipment that will listen to carrier messages and the set Answer supervision based on if prerecorded message or human voice? Anyone know thw name and manufacturer or price?
