1. VoIP

VoIP (Voice over Internet Protocol) carries voice and multimedia over IP networks instead of legacy phone lines. Packets not circuits. Software-driven, flexible, and everywhere.

Why It's Important

It slashes costs, scales fast, and unlocks features like HD voice, video, messaging, and seamless mobility across sites and devices.

How to Improve VoIP Skills

To lift VoIP quality and resilience, focus on the network first, then endpoints:

1. Right-size bandwidth: Plan for busy-hour call volume, overhead, and growth. Avoid congestion before it bites.
2. QoS end-to-end: Prioritize RTP/SIP, control jitter/latency, and honor DSCP across WAN and LAN.
3. Pick smart codecs: Use Opus or G.722 for quality; G.711 for simplicity; low-bitrate codecs when links are thin.
4. Lock down signaling/media: Enable TLS for SIP and SRTP for media. Harden SBCs, disable unused services, and rate-limit.
5. Monitor continuously: Track MOS, latency, jitter, packet loss. Alert on anomalies. Validate changes with synthetic calls.
6. Keep firmware current: Phones, softclients, PBX, SBC, gateways—patch routinely.
7. Avoid unnecessary VPNs: Use them for security mandates, not “quality.” They often add latency and jitter.

Small tuning, big gains. Users will hear the difference.

2. SIP Trunking

SIP Trunking connects your PBX to the PSTN over IP using the Session Initiation Protocol. Voice, video, and messaging ride the same rails.

Why It's Important

Lower costs than PRI, elastic scaling, failover options, and simpler multi-site architectures. It’s the modern dial tone.

How to Improve SIP Trunking Skills

1. Assess bandwidth and concurrency: Size trunks for peak calls plus headroom. Separate voice from data where possible.
2. Tighten QoS: Prioritize SIP signaling and RTP media. Police, shape, and preserve DSCP across links.
3. Harden the edge: Deploy an SBC, restrict IPs, enable TLS/SRTP, use strong auth, and apply rate limits.
4. Plan redundancy: Dual providers or diverse paths. Configure DNS SRV, geo-redundancy, and PSTN fallback.
5. Maintain and patch: Keep trunks, PBX software, and SBC firmware up to date. Test after changes.
6. Monitor and test: Watch call setup success, ASR, PDD, jitter, and packet loss. Run periodic failover drills.

Reliable trunks mean clear calls and fewer 2 a.m. emergencies.
