The PORTech MT-358 is a Fixed Wireless Terminal that supports FXS, FXO and GSM interfaces and can connect to a VoIP system , PSTN or VoIP gateway . The MT-358 supports 8 GSM concurrent channels, up to 8 calls can be live when 8 SIM cards are inserted.
Features
- Auto-select most economic route - The MT-358 automatically routes calls out over GSM or PSTN, depending on the destination.
- 8 Channel - Up to 8 SIM cards allow for eight GSM channels to be active at a time.
- Polarity Reversing function

- Follow Me - PSTN to GSM and GSM to PSTN
The PORTech MT-358 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-358 FWT 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-358 also works in reverse - routing incoming GSM calls to a PSTN number using the analogue line.
When a telephone is connected via FXS, calls can also be routed by either GSM or PSTN. The MT-358 can automatically check if the dialed number is on the network and if so, then the call will go out over the lower cost GSM rate; if not the call will go out over PSTN.
