NGN protocols include: SIGTRAN, MGCP, H.248, H.323, SIP and ISUP. SIGTRAN protocol group is used when ss is interconnected with PSTN, over which the ISUP protocol is borne. MGCP and H.248 protocols are used for interconnection with various MGs. H.323 and SIP protocols are used for interconnection among SoftSwitch devices, and meanwhile, H.323 can also be used for interworking with H.323 media terminal, while SIP can be used for interworking with SIP terminal.
