Fully Automatic Call Router for additional cost savings

The MT-354/ MT-358 has the ability to choose a route automatically. When you dial out from the MT-354/ MT-358, it will check number and see if it belongs to the Inter-Network number. If yes, then it will dial out from cellular and provide two “beep” tones to ensure it dialed out cellular. If not, it will dial out from the PSTN line.
