Description
Reviews

OpenVox upgraded the GSM gateways module , use with the VS-GWM420 Switch Board, with better performance that access to web quickly and no need to consider the cluster problem. Openvox have still have the old GSM module version now, maybe the new version will replace the old version gradually.

The Openvox new switchboard V2 (GWM420) can support GWM420G/W/L and GWM820O/S module ,and also support GWM400G/W, GWM800O/S, GWM801O/S, but you can't use GWM420G/W/L and GWM820O/S at same chassis, you only can choose one kind module at same chassis , GSM module GWM420G/W/L or analog module GWM820O/S.

If you want to use both analog module and GSM module, you can use old switchboard with old GSM and analog module, such as GWM400G/W and GWM800O/S, it can use both at same chassis.
One things should be mention, if you use the new version chassis (go with VS-GWM420 Switch Board ), you can use the both old version and new version GSM module with it. But the old version chassis only can support old GSM module.The new version is a little bit expensive than the old.
