UMG 104

User Media Gateway with 1 E1/T1, 4 gateways ETH, SAS and SBC


UMG 104 is a user media gateway, ideal for small and medium businesses that wish to have VoIP telephony benefits, using a highly reliable and affordable device.

With UMG 104, you can connect to up to 3 VoIP carriers with a dedicated link, assigning a region to each one of them and, thus, dramatically reducing expenses with national and international calls, when compared to regular rates. The dedicated physical connection with the carrier enables better performance for the links and, consequently, for the current calls. Other use cases: you can interconnect extensions found in the business headquarters and in the branches, anywhere in the globe, allowing facilities to call each other through the Internet at zero cost; you can apply it to VoIP carriers that charge per minute so as to make the services more professional; among others.
