UMG 102

User Media Gateway with 1 E1/T1, 2 gateways Ethernet Giga and SAS


UMG 102 is a user media gateway ideal for small businesses who wish to enjoy the benefits of VoIP telephony using a low-cost, reliable device.

UMG 102 allows you to connect to a VoIP carrier, significantly reducing expenses with national and international calls, when compared to regular rates.

Some of the UMG 102 use cases include: you can interconnect all the internal extensions of a company, including the headquarters and branches all over the globe, so that workers can call each other over the Internet at zero cost; it can also be used by VoIP carriers who charge per minute, so as to make the services more professional; among others.

UMG 102 also ensures the continuity of your telephony communications when your IP PBX becomes unavailable by assuming its basic functions, such as making and receiving external calls, calls between internal extensions and call transfer. We are talking about the Survivability feature, an optional resource available for purchase.*
