It allows the users to make eight simultaneous calls from IP phones to GSM or GSM to IP phones. The PORTech MV-378 is a quad-band device, which should work in most countries.

The Portech MV-378 can take calls from the user - mobile or landline - and forward the call via the net to an IP PBX, VoIP gateway or VoIP service provider and onto SIP phones, analogue phones, PSTN or mobile.

Easy Two Stage Dialling
A user can dial the number of the SIM inside the gateway, the MV-378 then gives the user a dial tone and DTMF signalling is then used to link up the desired destination. The MV-378 then routes the call via VoIP or GSM depending on the configuration. Everything can be set up / configured via the web admin.

When an VoIP phone and the MV-378 both register to the SIP proxy server or Asterisk PBX, you can dial any destination number from the VoIP phone directly.
