Portech Mv-372q: 2 Ports Sip GSM Gateway For Quad Band

MV-372Q is a 2 channels VOIP GSM gateway for call termination (VOIP to GSM) and origination (GSM to VOIP) . It is sip based and compatible with asterisk. It can enable to make 2 calls simultaneously from IP phones to GSM networks and GSM network to IP phone.
Major function:
1. VOIP (sip) , GSM conversion. (mv-372)
3. 50 sets of LAN--> mobile routes setting, 50 sets of mobile--> LAN routes setting.
4. Voice response for setting and status (dial in from mobile) .
5. For call termination (VOIP to GSM) and origination (GSM to VOIP) .
6. Standard sip (rfc2543, rfc3261) protocol, communicates with other gateway or PC
7. All functions can be set on web.
* we have WAN and LAN interface. So it can stack
