1)Media transfer between the PSTN and IP network;
2)Provide tranform between SS7, ISDN PRI ,V5.2 signalling and SIP protocol;

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, PRI,V5.2,CAS etc.

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.
