The PORTech MV-370 is a single channel VoIP GSM Gateway which allows for call termination (VoIP to GSM) and call origination (GSM to VoIP.) The gateway fully supports Asterisk, it connects as a SIP trunk and allows you take advantage of low cost calls to mobile phones via the SIM card. The MV-370 supports 1 SIM card so supports one GSM channel at a time.
The MV-370 can receive calls from the user via mobile and then forward the call via the Internet to an IP PBX, VoIP gateway or ITSP, this can be a single call to a predefined number or if required a simple 2-stage dialling. The user dials the number of the SIM and the gateway then presents the user with a dial tone, the user can then dial the desired number, the MV-370 then routes the call via GSM or VoIP depending on the settings that have been configured. All settings can be configured via a Web interface.
When an IP phone and the MV-370 both register to the SIP proxy Server or Asterisk server, you can dial any destination number from IP phone directly.
