We are selling a number of Vierling VTMpro VoIP to GSM gateways in excellent condition. The units have the latest version of the software and the Wavecom GSM boards that allow the IMEI to follow the SIM. We can provide either the SIM32 boards which allow the device to work as a standalone gateway with 8 SIMs per channel OR the SIM emulation boards that work with the Vierling SIM Server.

The VTMpro runs on a Linux platform and collects all CDRs locally. All major CODECs are supported including G.711, G.723, G729 (all variants). These gateways are available for collection in the UK or we will ship internationally at cost.
