VoIP to GSM cellular gateway

Monday, 03 August, 2009



The MultiVOIP GSM SIP-to-Cellular gateway routes voice calls between IP-PBX based telephone systems and GSM networks.

By integrating a GSM connection into your existing network, you can realise substantial savings on mobile Fleet Plans, or where your carrier provides low-cost mobile calls to specific destinations.

As an added benefit, the MultiVOIP GSM can serve as a backup connection to remote VoIP sites in case of external Internet failure. By placing MultiVOIP GSM units at all facilities, you can direct your VoIP traffic over a cellular connection, avoiding the need to route traffic to the PSTN.
