Package sccp provides simple and painless handling of SCCP (Signaling Connection Control Part) in SS7/SIGTRAN stack, implemented in the Go Programming Language.
This is still an experimental project, and currently in its very early stage of development. Any part of implementations(including exported APIs) may be changed before released as v1.0.0.
Run go mod tidy to download the dependency, and you're ready to start developing.
