Overview

Next-Generation Network

Modern international gateways must support legacy TDM, VoIP and LTE/VoLTE at the same time. EVO Solution designs and implements NGN architectures with MSS, MGW, SBC, SG, DNS/ENUM, NTS and DSC to interconnect seamlessly with domestic and international carriers.

Supporting SIP/SIP-I, H.248, RTP/IP, ISUP/TDM and Diameter, the platform delivers cross-network voice services — including LTE/VoLTE roaming — with quality and security at the network edge.
