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 & MediaEF for RTP; jitter buffers; DSCP preservation; SBC media anchoring; TURN/ICE for NAT.

📐 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) |

🛠️ 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.
✅ Pre-Engagement Checklist
🔄 Where Hosted Voice Fits (Recursive View)
1) Grammar — voice rides /connectivity & the /networks-and-data-centers fabric.

Key terms in plain language
Open a term for a concise explanation of language used on this page.
Fiber Internet
Internet delivered through strands of glass using light. Fiber commonly supports high capacity, low latency, and strong upload performance, but availability must be confirmed for the exact address.
Bandwidth
The amount of data a connection can carry in a given time, usually measured in Mbps or Gbps. More bandwidth supports more users, devices, and simultaneous applications.
Latency
The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.
SD-WAN
Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.
Unified Communications (UCaaS)
A cloud-based combination of business calling, messaging, meetings, presence, and collaboration tools managed as one communications service.
SIP Trunking
A service that connects a business phone system to the public telephone network using Internet Protocol, replacing or supplementing traditional phone lines.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Zero Trust
A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.
