Legacy Telecom

Fax, Modem, IWF and VoIP Gateway

Creating a ubiquitous media experience

The  uptake of next-gen technologies , particularly on the enterprise front, can be long. Consequently, fax is still used for legal communications, modems are preferred for remote financial services, and telecom operators are still required to provide cross-platform connectivity between fixed and mobile networks.

Overcoming those legacies become a key element when evaluating the upgrade of an existing core-infrastructure. Surf’s technology arsenal provides enterprises with powerful, complete  and customized solutions – helping them to reach the next gen technologies.
