SIP-native voice agents for any PBX
Low-latency, locally-hosted voice agents that register over SIP like any extension. Private by design for HIPAA-sensitive deployments, with the technical control your team expects.
Free account. No credit card to get started.
Built for teams who care how it works
The details that matter when you put voice AI in front of real customers and regulated industries.
Low latency
Tight ASR → LLM → TTS turn timing for natural, interruptible conversations that feel human on a live call.
Local models, private by design
Run locally-hosted speech and language models so audio and PII stay in your environment — a practical fit for HIPAA-sensitive workloads.
SIP-native PBX integration
Registers as a standard SIP extension. Point any compliant PBX at it — no proprietary connectors, no vendor lock-in.
Two ways to grow with VoxLayer
Offer voice AI under your own brand, or introduce customers to VoxLayer and earn a commission. Both tracks start with a short application and interview.
Whitelabel reseller
Your brandBest if you already sell services and want conversational voice AI as part of your own product line.
- Your brand, your pricing — Proposals carry your company name, logo, and tagline. You set what customers pay.
- Contracted discount & margin — You pay VoxLayer at a negotiated discount. The gap between what you charge and what you pay us is your margin.
- You own the customer — You provide tier-1 support and billing. Agents live on your account; we support you on platform issues.
- Whitelabel agreement — After acceptance you digitally sign our reseller agreement (with your discount filled in) before using Opportunities and demos.
Referral partner
Our brandBest if you want to recommend VoxLayer without running billing, support, or your own branded product.
- Sell under the VoxLayer brand — Proposals use our brand and list pricing. The customer contracts and pays VoxLayer directly.
- Commission on closed deals — Earn 10% of the first 6 months of revenue on month-to-month accounts, or 10% of the full contract price on annual / multi-annual accounts (still billed monthly). Credited to your Stripe account after the customer’s 3 monthly payment.
- We own the customer — Converted agents become direct VoxLayer accounts (marked as sold by you). Billing and platform support are ours.
- Referral agreement — After acceptance you digitally sign our referral partner agreement covering commission terms before sending proposals.

Real Customer Reviews
See what ITSPs, MSPs, and VoIP providers say about running voice agents on their PBX with VoxLayer.
As an early VoxLayer beta tester, I have been amazed at how well our agent has handled inbound calls for my computer services business. She has been able to answer simple questions and take messages when I am not available, much more of a human touch than an IVR.
Our reception agent has mainly been routing inbound calls and screening sales, which has been great. We have her tied into our slack and even embedded in our website for voice support, very cutting edge! Connection to our PBX took minutes, and configuring took less than an hour. Super happy here.
I work with StratusTalk reselling their PBX platform, and when they launched VoxLayer I got excited to see what new service I could sell to my customers. The demos blew me away, and I am in talks with multiple healthcare and hospitality clients to get agents as soon as we can install them!
