Clear Calls, Resilient Sites, Secure Numbers — With Evidence
Hosted Voice replaces legacy PBXs with cloud calling, collaboration, and contact-center that just works—at HQ, branches, WFH, and mobile—while meeting E911/NG911, PCI/HIPAA, and security requirements.
SolveForce designs and operates Hosted Voice that’s Zero-Trust by default, SD-WAN/QoS-aware, and audit-ready—so conversations stay clear and compliant.

🎯 Outcomes (Why SolveForce Hosted Voice)
- Crystal-clear calls — engineered QoS and media paths (LAN/WAN/edge).
- Everywhere reliability — branch survivability and dual-carrier WAN keep dial tone up.
- Compliance by design — E911/NG911, STIR/SHAKEN, lawful intercept procedures, retention policies.
- Operational clarity — real-time quality dashboards, fraud controls, and exportable evidence.
🧭 Scope (What We Deliver & Operate)
- UCaaS — enterprise calling, softphones, mobile apps, voicemail-to-text, meetings & messaging.
- CCaaS — IVR/IVA, skills/queues, WFM/WFO, call recording/redaction, analytics, CRM/ITSM integrations.
- SBCs & Interop — Teams/Zoom Direct Routing, legacy PBX coexistence, analog FXS gateways (fax/T.38, paging, elevator/alarms).
- Numbers & PSTN — DIDs/toll-free, LNP (porting), CNAM, multi-geo routing, geo-redundant carriers.
- E911/NG911 — dispatchable location, dynamic location for softphones/Wi-Fi, test-call runbooks.
- Edge & WAN — QoS policy, SD-WAN packet duplication/FEC for voice, private APNs for retail/kiosk use cases.
🧱 Building Blocks (Spelled Out)
- QoS & Media: EF for RTP; jitter buffers; DSCP preservation; SBC media anchoring; TURN/ICE for NAT.
- Fraud & Abuse: STIR/SHAKEN, dial-plan allow/deny, intl throttles, per-dest rate caps, geo/ASN blocks.
- Security & Identity: SSO/MFA to admin portals; ZTNA for admin & remote phones; device certificates; config in Git with approvals. → /ztna
- E911/NG911: LIS/HELD or provider API updates; per-DID address mapping; monthly test schedule with artifacts.
- Records & Privacy: encrypted recordings, retention & legal hold, tokenization/redaction for PCI/PII. → /dlp
- Survivability: local SBC/ATA for analog fallbacks; PSTN reroute on UCaaS outage; dual underlays via SD-WAN. → /sd-wan

📐 SLO Guardrails (Targets You Can Measure)
| KPI (p95 unless noted) | Target (Recommended) |
|---|---|
| Call setup (post-dial delay) | ≤ 1–2 s local • ≤ 2–4 s long-haul |
| One-way latency | ≤ 50 ms metro • ≤ 120 ms regional |
| Jitter (one-way) | ≤ 20–30 ms |
| Packet loss (sustained) | < 0.2–0.5% |
| MOS (narrow / wideband) | ≥ 3.9 / ≥ 4.1 |
| Trunk/tenant availability | ≥ 99.95–99.99% |
| E911/NG911 provisioning accuracy | = 100% of DIDs with test evidence |
| Evidence completeness (Sev-1/2) | = 100% (CDR/QoS logs/changes) |
SLO breaches auto-open tickets and trigger SOAR actions (reroute, throttle destination, rollback policy). → /siem-soar
🔒 Compliance & Privacy
- PCI DSS (if taking cards): CDE segmentation, tokenization/redaction, key custody (HSM/KMS), WAF for portals. → /key-management • /waf
- HIPAA (if PHI): BAAs, encryption & audit controls, retention policy.
- SOC 2 / ISO 27001: access, change, logging, incident evidence.
- STIR/SHAKEN: attestation & verification to combat spoofing.
📊 Observability & Evidence
- Voice quality: MOS, jitter/latency/loss, codec mix, jitter-buffer stats.
- Contact center: AHT, ASA, service level, queue abandons, sentiment (where enabled).
- Telephony: ASR/ACD, trunk utilization, 4xx/5xx by dest, fraud alerts, E911 test logs.
- Change & security: SBC/tenant diffs, admin actions (SSO/MFA), API keys rotation; all exported to SIEM with WORM options. → /siem-soar
🛠️ Implementation Blueprint (No-Surprise Rollout)
1) Assess users, numbers (DID/toll-free), sites, devices, PBX/SBC inventory; E911 gaps.
2) WAN & QoS: classify EF, SD-WAN duplication/FEC policy; bandwidth & PoE audits. → /sd-wan
3) Numbering: LNP plan, port windows, CNAM; dial-plan & extension policy; intl routing rules.
4) Security: SSO/MFA, ZTNA for admins; fraud controls; recording encryption & retention. → /ztna
5) E911/NG911: dispatchable location sources; test-call plan; monthly evidence cadence.
6) SBC & interop: Teams/Zoom/legacy PBX; analog FXS (fax/paging/elevator).
7) Pilot & rings: IT → champions → one site → region → global; success gates.
8) Train & cutover: user adoption, quick sheets; DND/forwarding policies; help-desk runbooks.
9) Operate: SLO dashboards; quarterly quality reviews; fraud drills; number lifecycle hygiene.
