The MultiVOIP® GSM SIP-to-cellular gateway routes voice from your internal network to a GSM connection.  By integrating a GSM connection into your existing network, you can realize substantial savings on long distance toll charges. As an added benefit, the MultiVOIP GSM serves 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 and do not need to route traffic to the PSTN. The MultiVOIP GSM gateway is available in a 2-port model, and maximizes the investments you've already made in your data and voice network infrastructure.
