2. VoIP Systems

VoIP (Voice over IP) carries voice and rich media over IP networks. It collapses voice, video, and data onto one fabric, unlocking flexibility, scale, and cost control.

Why It's Important

It powers hybrid work, integrates with apps, and reduces spend—without sacrificing quality if the network is shaped for it.

How to Improve VoIP Systems Skills

1. Engineer the network: Prioritize real-time traffic with QoS (mark EF, tune queues). Control jitter, packet loss, and latency end to end.

2. Deploy SBCs: Enforce policy, handle NAT traversal, protect signaling/media, and interwork with carriers.

3. Plan redundancy: Active/standby call control, multiple trunks, geo-redundant SIP and DNS SRV failover. Monitor OPTIONS keepalives.

4. Choose codecs smartly: Balance bandwidth and quality (e.g., G.711 for LAN, compressed codecs for WAN). Validate jitter buffer behavior.

5. Harden security: TLS for signaling, SRTP for media, fraud analytics, strong auth, and strict dialing policies.

6. Observe relentlessly: Track MOS, R-Factor, RTT, jitter, and session ladders. Alert on anomalies before users do.

7. Regulatory readiness: E911/NG911 accuracy, call recording policies, retention, and lawful intercept where required.
