Sangoma W400 GSM Card is the latest addition to the computer telephony board portfolio that adds GSM voice connectivity and SMS capabilities to IP-PBX applications.

Sangoma W400 also offers the possibility to send SMS messages over the GSM network, enhancing the IP-PBX to act as an SMS gateway. For added flexibility, SMS messages can be sent while a voice conversation is active on the GSM port.
Sangoma W400 has a unique design that allows access to SIM cards directly from the front of the card. This added flexibility removes the need to open up computer systems to access SIM cards.
