SIGTRAN
SIGTRAN is a set of rules and methods that helps telephone networks connect to internet-based networks. Think of it as a translator that allows traditional phone systems to communicate with modern internet networks. It's particularly important for mobile phone networks and helps phone companies provide reliable services when calls or messages travel between different types of networks. When you see this term in a resume, it usually means the person has experience working with telephone network systems and understands how to connect older telephone equipment with newer internet-based systems.
