Converged Networks for Calling, Collaboration, and Everything IP — Engineered, Secure, and Proven

“Voice and data” no longer live on separate planets. Your calls, meetings, messages, apps, databases, video, AI pipelines, and IoT all ride the same IP fabric.
SolveForce designs and operates converged Voice & Data as a system: LAN/WLAN/CAN/MAN, SD-WAN overlays, fiber & wireless access, SIP/SBC & UC/CCaaS, QoS end-to-end, Zero-Trust access, and evidence pipelines so every packet class, change, and test is measurable and auditable.

🎯 Outcomes We Optimize

• Clear voice, fast apps — low jitter/loss for calls while data stays snappy.
• Resilience by design — dual underlays (DIA + 5G/Fixed Wireless/Coax/GPON), SD-WAN packet duplication/FEC, Anycast ingress for UC/CCaaS.
• Security by default — TLS/SRTP, STIR/SHAKEN, ZTNA for admin access, SASE for web/SaaS, NAC 802.1X at the edge.
• Evidence on demand — MOS/jitter/loss, throughput/latency, DSCP preservation, RFC 2544/Y.1564, E911 tests, SBC diffs—exportable to SIEM.
• Predictable cost — right-sized access, QoS policies, and TEM/FinOps dashboards.

🔢 Planning Tables (quick math for Voice & Data)

1) Voice codecs & bandwidth (per call including IP/UDP/RTP & L2 overhead)

Codec	Per-Call BW (approx)	Quality	Notes
Opus (wideband)	30–50 kb/s	🎧 High	Preferred on softphones; resilient
G.722 (wideband)	~100 kb/s	🎧 High	Many desk phones
G.711 μ/A (narrowband)	~100 kb/s	🎙️ Legacy	Easiest interop
G.729 (narrowband)	30–40 kb/s	📞 OK	Lower fidelity—use sparingly

Safe calls per 1 Mb/s (≈70% planning utilization):

• Opus 24 kb/s → ~18–22 calls/Mb/s
• G.711/G.722 → ~7–8 calls/Mb/s
  (Always reserve headroom for signaling & spikes; WAN encapsulations may add overhead.)

2) QoS class map (end-to-end)

Class	DSCP	WMM	Traffic	Targets
EF	46	AC_VO	Voice RTP / emergency alerts	Jitter ≤ 20 ms, Loss < 0.3%
AF41/42	34/36	AC_VI	Video conferencing / screen share	Jitter ≤ 30 ms, Loss < 0.5%
AF31/CS3	26/24	AC_VI/BE	Signaling, control, critical apps	Low latency preferred
BE/CS0	0	AC_BE	General data / web	Best effort
CS1	8	AC_BK	Background / bulk	Rate limit if needed

3) Per-user data planning (typical p95)

App	p95 Throughput	Notes
Web/SaaS mix	1–5 Mb/s	Bursty; cache/DNS tuning helps
Video conf (HD)	1.5–3 Mb/s	Per stream; add 10–20% for headroom
Screen share	0.3–1 Mb/s	Often alongside video
File sync burst	5–20+ Mb/s	Schedule windows / rate limit
VDI (task/knowledge)	0.5–2 Mb/s	Latency-sensitive

🔐 Security & Compliance (baked in)

• Transport: TLS signaling + SRTP media; modern ciphers.
• Caller trust: STIR/SHAKEN attestation/verification; inbound fraud filtering.
• Access: ZTNA for admin consoles; NAC 802.1X; device posture (MDM/UEM + EDR); SASE for roaming.
• Edges: WAF/Bot for portals/APIs; DMARC → p=reject; DLP for transcripts/recordings.
• Compliance: PCI DSS (pause/resume, DTMF masking), HIPAA (encryption, minimum necessary, BAAs), SOC2/ISO/NIST evidence packs.
  → /pci-dss • /hipaa • /grc

📐 SLO Guardrails (Voice & Data you can measure)

Domain	KPI / SLO (p95 unless noted)	Target
Call setup	Post-Dial Delay (local/long-haul)	≤ 1–2 s / ≤ 2–4 s
Voice quality	MOS (wideband)	≥ 4.1
Jitter / Loss	One-way / sustained	≤ 20–30 ms / < 0.3–0.5%
SD-WAN	Brownout steer time	≤ 1–3 s
Data latency	Branch→cloud (regional)	≤ 20–50 ms
Wi-Fi join/roam	Assoc+802.1X+DHCP / handoff	≤ 2–4 s / ≤ 50–150 ms
Security	ZTNA admin attach	≤ 1–3 s
Trust	DMARC rollout	p=reject ≤ 60–90 days
Availability	Site effective (dual underlays)	≥ 99.95%
Evidence	Logs/tests → SIEM	≤ 60–120 s

If a guardrail slips, SOAR auto-opens a case and runs guarded plays (reroute, enable packet duplication, codec shift, WAF rule, re-key, rollback), attaching artifacts. → /siem-soar

🔁 Use-Case Patterns

• Branch @ Scale (Voice + Data) — DIA + 5G/Fixed Wireless, SD-WAN duplication for EF, Anycast UC ingress, SASE breakouts; PCI/HIPAA overlays where needed.
• HQ/Colo/Cloud Edge — 10/40/100G DCI, SBC clusters, private on-ramps, WAF/API security; DR runbooks.
• Retail/Clinics — GPON/coax primary + LTE tertiary; captive portal Wi-Fi; PCI tokenization; HIPAA DLP for transcripts.
• Events/Pop-ups — 5G primary, packet-dup voice lanes, portable SBC or UCaaS tenant; quick demobilization kit.

---

🧱 Design Notes & Best Practices

• Keep EF clean — mark at source, trust at access, verify in WAN; don’t over-classify.
• Limit SSIDs — 2–4 per band; voice SSID gets EF; disable low basic rates.
• Use packet duplication selectively — high-value queues and executives; cap for cost.
• Engineer diversity — separate laterals/POPs/providers; add satellite tertiary where geography demands.
• Anycast ingress for UC/CCaaS — closest, healthiest edge wins; withdraw on health.
• Object-Lock backups for configs and recording stores; test restores.

• Cloud & on-ramps (DX/ER/Interconnect POPs, regions, Private Endpoints only?)
• Compliance (PCI/HIPAA/SOC2/ISO/NIST/etc.), evidence retention needs
