Specifications

1)8 E1, Provide transform between SIP protocol and SS7, PRI signaling;
2)Media Transfer between the PSTN and IP network;

Description:

NC-MG800-208 which is the largest capacity Media Trunk Gateway contains 2 independent module (each module have 4 E1). It supports 256 channels VoIP concurrency and SIP protocol. The signaling support SIP, H323, SS7, ISDN PRI Signaling.

 

NC-MG800-208, a new generation media transform device which is designed by NiceComm company, combines a traditional pbx switching CTI platforms and other value-added business functions into one. According to the concept of carrier-grade embedded operating system and module structure, NC-MG800-208 is flexible, easy to install, cost effective features; and users are more easily to manage.
