NICEUC VoIP GSM Gateway is for operators, enterprises, SOHO, virtual operators to offer affordable VoIP solutions. It is a full-featured IP-based GSM wireless network of VoIP gateways, which can provide stable network configuration, powerful features, good voice quality. This GSM Gateway uses the industry's popular chip technology to support E1, GSM / CDMA / WCDMA / 4G LTE, SIP, IMS interface, supports maximum 4 ports E1 / T1, 96 ports GSM / CDMA / WCDMA / 4G LTE, 128 SIP trunks. Our GSM gateway is not only full compatible with Asterisk and other leading soft switch, but also is a cost-effective gateway for call termination (VoIP to GSM) and origination (GSM to VoIP).
