DMT-V: 8/16/24/31 ports VoIP GSM Gateway 

~with CDR,LCR,Remote Monitor
~GSM ,CDMA can be combined in one DMT-V
DMT-V accepts incoming call from VoIP and choose one GSM channel to dial out according to the prefix of the destination mobile number.
In this way, we can have least cost routing (LCR).
DMT can provide Call Detail Record (CDR) for traffic and accounting management.
User can remote monitor traffic via VNC.

GSM Frequecny:
Dual BAND:900/1800 MHZ
Tri Band: 900/1800/1900MHZ
Tri Band: 850/1800/1900MHZ
Quad Band:900/1800/1900/850MHZ

CDMA 2000(800MHZ)




each VoIP channel will connect to the corresponding output GSM Port.
Auto-routing for the same network: system will search for the GSM port of the same network to dial out, according to the prefix of the out-dialing number from the incoming VoIP channel.
Password validation: operator has to input the correct password for further setup of the system parameters.
Hiding the CLID: user can choose whether to hide the CLID of the GSM port or not.
Calling time: user can assign the calling time for each sheet of the SIM card. When the time runs out, system will block this GSM port, or switch to next unused SIM card (in the case that SCE is installed).
Call detail record (CDR): the CDR is provided for further use of the billing system.
Backup of CDR: user can set up the path of CDR backup. Simulate ring back tone: user can set up whether to simulate ring back tone or not.
SCE test: system can auto-test the SIM card switching function to ensure the successful switchover without letting the SIM card be used repeatedly.
ASR statistics: system will provide a time-varying ASR analyzing report for easy understanding the communication traffic.
Besides VoIP to GSM,you may also apply GSM to VoIP (two ways).
