What will I learn?

This Telephony Course provides a straightforward, hands-on guide to setting up, rolling out, and keeping up modern voice setups. You go learn key signalling, SIP trunks, dial plans, numbering, SBCs, gateways, QoS, codecs, and how to fine-tune call quality. Build up skills in reliability, security, monitoring, handling incidents, and planning migrations so you can deliver steady, top-notch voice services across different sites and networks.
