The PORTech MT-354 is an FWT that supports FXS, FXO and GSM interfaces. The MT-354 can connect to a PBX, the PSTN or VoIP gateway. Supporting 4 GSM channels at once, up to 4 calls can be passing through concurrently when 4 SIM cards are used.

PORTech MT-354 Features

  • Auto-select most economic route - The MT-354 automatically routes calls out over GSM or PSTN, depending on the destination.
  • 4 Channel - Up to 4 SIM cards allow for four GSM channels to be active at a time.
  • Polarity Reversing function
  • Set GSM dial-out code amount
  • Limit of communicating time
  • GSM simulated echo-bell function
  • Follow Me - PSTN to GSM and GSM to PSTN

The PORTech MT-354 can connect to your analogue phone line and divert calls to your mobile via its SIM card. Call forwarding rates to mobiles via the PSTN are typically expensive,therefore - when out of the office - calls to the office analogue line would be missed or forwarded to your mobile at considerable cost.

The MT-354 can transfer all incoming calls using its FXO port to GSM and connect calls directly to your mobile using more cost-effective mobile-to-mobile tariffs.

Many mobile operators offer great value deals on same network calls. Thus, if a SIM of the same network as your mobile is used, these inclusive minutes or low call rates can be used when routing calls to your mobile.

The MT-354 also works in reverse - routing incoming GSM calls to a PSTN number using the analogue line.

When a phone is connected via FXS calls can also be routed by either GSM or PSTN. The MT-354 can automatically check if the dialed number is on the network, and if so, the call will connect over the lower cost GSM tariff (sounding 2 beeps to the user's handset to confirm); if not, the call will connect over PSTN.
