Your first week with VoxSun.
A typical VoxSun deployment goes from signed order to full team live in five business days — without an IT project, without downtime, and without re-training your staff.
Built on VoxSun carrier infrastructure.
Unlike providers that rely exclusively on third-party communications platforms, VoxSun operates carrier-grade telecommunications infrastructure registered with the FCC (USA) and CRTC (Canada) since 2010. Owning the telecom layer means better call quality, better deliverability, and no reseller markup.
Owned SIP Trunk Network
VoxSun operates its own carrier-grade SIP trunks across Canada, the USA, Europe, and Africa — no third-party telecom reselling, no capacity limits.
STIR/SHAKEN Attestation A
Every outbound call carries STIR/SHAKEN Level A verification — the highest standard. Calls land on caller ID as verified, not spam-flagged.
6 Carrier Nodes — 3 Continents
Canada (Montreal, Toronto) · USA (New York, Dallas) · Europe (Paris, Frankfurt). If one node fails, calls re-route automatically in under 800ms.
End-to-End Encryption
All voice traffic uses mTLS signaling and SRTP AES-256 media encryption — meeting the security requirements of enterprise and regulated-sector deployments.
ActivVoice HD Audio
Wideband codec technology delivers MOS ≥ 4.0 voice quality — significantly clearer than standard telephone audio. Included on every plan.
Instant Failover
If your internet drops, calls automatically roll over to mobile, another office, or voicemail. Zero calls dropped during infrastructure events.
How VoxSun delivers every call.
Five carrier-grade layers between your customer's voice and the destination — every call, every time.
- 01CustomerInbound or outbound call originates from a desk phone, mobile app, browser softphone, or AI voice agent.
- 02VoxSun EdgeGeo-redundant edge nodes authenticate the call, sign it with STIR/SHAKEN Attestation A, and route it onto the VoxSun backbone.
- 03Carrier NetworkCalls travel across VoxSun-owned SIP trunks — not rented from a third party — across 6 nodes on 3 continents.
- 04ActivVoice HDWideband codec encodes audio at MOS ≥ 4.0 with packet-loss concealment and jitter buffering tuned for voice.
- 05DestinationCall lands on the recipient as a verified, HD-quality call — desk phone, mobile, PSTN, or another VoxSun extension worldwide.

Why businesses replace RingCentral, Zoom & 8x8.
The buyers already shopping rarely ask 'which VoIP is best?' — they ask 'why pay for five disconnected tools when one carrier-grade platform includes them all?'

Who is VoxSun for?
VoxSun is built for organizations where every call matters — and where the cost of a missed lead, a dropped call, or a fragmented stack is measured in revenue.

Brokerages, teams, and agents who need every listing inquiry answered — even after hours — with the same number on desk, mobile, and browser.
Legal
Law firms that require encrypted communications, recording controls, and STIR/SHAKEN-verified outbound calls for client trust.
Healthcare
Clinics and multi-site providers needing secure communications, dial-in access for patients, and reliable carrier-grade voice.
Call Centers
Outbound and inbound operations that depend on Attestation A verified caller ID, BOOST capacity, and AI qualification at scale.
Financial Services
Advisory firms, brokers, and lenders requiring audit logs, role-based permissions, and compliance-ready recordings on every line.
Multi-Location Businesses
Franchises, agencies, retail, HVAC and service businesses unifying every office on one number plan, one admin portal, one invoice.
What if my migration fails?
The biggest objection in telecom is fear of a botched cutover. VoxSun runs every migration with a parallel-routing model, a dedicated specialist, and documented rollback procedures — your existing numbers stay live until you say go.
Existing numbers stay active
Your current carrier keeps routing calls during porting. Customers feel zero interruption — there is no period when your number stops working.
Calls continue routing
We forward inbound traffic from day one of the project. The cutover flips the signal — it does not interrupt service.
Porting handled by VoxSun
Paperwork, carrier authorization, scheduling, and confirmation are managed end-to-end by the VoxSun onboarding team — not by you.
Rollback procedures available
If any anomaly is detected during cutover, traffic is reverted to the previous carrier within minutes using documented rollback steps.
Dedicated onboarding specialist
A named human is responsible for your migration — porting status, device shipment, user provisioning, and go-live verification.
Migration plan delivered before you commit
Every prospect receives a written migration plan covering numbers, devices, users, timeline, and risk before signing anything.

What is BOOST?
BOOST is VoxSun's dynamic capacity engine — included on every plan at no extra cost. It automatically activates additional call capacity during peak demand and scales back when traffic decreases, so you never pay for unused capacity and never miss a call during a peak period. BOOST is one of the reasons VoxSun is meaningfully less expensive than traditional per-seat VoIP: instead of buying a permanent seat for every employee 'just in case', you provision a base of carrier-grade lines and let BOOST handle spikes in real time.
Auto-scales during peaks
When active concurrent calls approach your base capacity, BOOST activates additional lines within seconds — no manual intervention.
Scales back when quiet
As call volume drops, BOOST releases the extra capacity. You only ever pay for your committed base lines.
Included on every plan
BOOST is not an upsell or premium tier. Every VoxSun plan — Starter, Growth, and Pro — ships with BOOST enabled.
Carrier-grade behind the scenes
Extra capacity is drawn from VoxSun's owned SIP trunk network with the same STIR/SHAKEN signing and HD audio.
