For a CCNA-focused look at real-time audio/video conferencing, here is a concise, practical network checklist that complements 's software suggestions and responds to 's question about what the network must provide.

A minimal, production-capable stack includes: a signaling/proxy server (SIP or websockets), a media plane (MCU or SFU/media bridge), NAT-traversal services (STUN/TURN/ICE), an edge Session Border Controller (SBC) or firewall rules, and monitoring/RTCP for quality stats. Use SRTP/DTLS and TLS for transport where possible. Plan capacity: one-way latency ideally <150 ms, jitter under ~30 ms, and packet loss <1% for good voice quality.

On the routing/firewall side (CCNA tasks): disable problematic SIP ALG on consumer routers, open SIP ports (5060/5061) and the high-port RTP range your media server uses, and apply QoS—mark voice as DSCP EF and give it low-latency priority; put voice/video on separate VLANs or classes. Avoid RTP fragmentation by checking MTU and packetization settings. For wireless, enable WMM and prioritize real-time streams.

Lab and troubleshooting tips: build a small lab with two softphones, a SIP proxy and a TURN server; introduce delay/loss to test. Capture with Wireshark using a display filter like sip || rtp || srtp or a capture filter such as udp portrange 10000-20000 (adjust the port range to your server). Watch RTCP reports for jitter and loss, and verify DSCP markings end-to-end. Common failures are blocked ephemeral media ports, SIP ALG mangling headers, missing QoS policies, and asymmetric routing.
