The PORTECH
MV-372 is a dual channel VoIP GSM Gateway which allows for
call termination (VoIP to GSM) and call origination (GSM to
VoIP.) The Portech MV-372 VoIP GSM 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-372
supports 2 SIM cards so supports two GSM channels at a time.
It allows the users to make two simultaneous calls from IP
phones to GSM or GSM to IP phones.
The Portech
MV-372 can receive calls from the user (via mobile or landline)
and then forward the call via the Internet to an IP PBX, VoIP
gateway or ITSP (such as ourselves) and then onto SIP phones,
analog phones, PSTN or a mobile phone.
Simple
2-stage dialling:- The user dials the number of the SIM thats
inside the MV-372, the gateway then presents the user with
a dial tone, and DTMF signalling is then used to pick up the
desired destination. The MV-372 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 Portech MV-372 both register to the SIP proxy
Server or Asterisk server, you can dial any destination number
from IP phone directly.
