The High-density Universal Media Gateway


Matrix SARVAM UMG is a universal connectivity media gateway offering connectivity to VOIP, GSM/3G, T1/E1 PRI, ISDN BRI and POTS networks on a single platform. Matrix SARVAM UMG links an organization’s existing infrastructure to the new age communication networks ensuring right connectivity and least cost for each and every call. The gateway is an ideal solution for workplaces such as call centres, ISP, ITSP, wholesale terminators and organizations experiencing high call traffic on per-day basis.

Universal routing combined with least cost routing, telephony costs can be significantly reduced by selecting the most economical network for call routing based on number, time, network, port and combinations of each. The universal slot architecture allows selection and configuration of interface options to match the exact call traffic requirements of an organization.
