What will I learn?

This course offers a hands-on, brisk introduction to contemporary voice communication systems, spanning traditional PSTN and TDM PBXs through to VoIP, SIP, and RTP protocols.

Key topics also include ensuring quality of service, bolstering security, implementing redundancy, handling emergency E911 services, and conducting practical tests to confidently roll out dependable, top-notch telephony setups.
