E1/T1 PRI ISDN Trunking Gateway

E1/T1 PRI ISDN Gateway provided an easy solution. It is the idealistic solution for carrier and enterprises in the current ISDN switch-off trend. Changing the traditional PBX system will be unnecessary. Whether it is connected to PSTN or PBX, the trunk Gateway provides a reliable and bandwidth-efficient solution that leverages the interoperability, scalability and enhanced services capability of the industrial standard SIP protocol.
