System prompts, models, call flows, tools. Configure once, ship to 15 sovereign hubs. 30+ models included.

Built with the leading voice ecosystem

The full stack

One API, one contract

Models, telephony, and compliance under a single agreement.

Model flexibility

30+ low-latency models. Run a different model per language and switch mid-deployment.

Regional compliance

HIPAA compliant. GDPR compliant. ISO 27001 certified. SOC 2 Type II in audit.

Automatic failover

Providers go down at 2am. Your calls don't.

Continuous optimization

What runs on every call

Every turn, every call, no pipeline code.

PII redaction

Names, numbers, and identifiers stripped before audio reaches your models or logs.

TTS optimization

Repeated TTS responses served from cache. Provider never gets called.

Context routing

Simple turns stay local. Complex turns hit your LLM. Fewer model calls per conversation.

Automatic failover

A provider degrades mid-call, the next turn goes elsewhere.

Transcripts

Region, provider, model, cost, latency. Logged per step, per call.

Analytics

Cost and latency tracked against baseline. Dashboard shows the delta.

In-region compute

Runs where your callers are

Choose a regional endpoint for your voice infrastructure. One line decides where everything runs.

Base URL

How it works

Three steps from config to production agent

All data stays in your chosen region from call start to call end.

Configure

System prompt, model selection, call flow, tool integrations. All in the dashboard.

Connect

Plug in via SIP. Connect to your CRM, ticketing system, or knowledge base via API.

Ship and monitor

Real-time latency dashboards, call transcripts, and compliance audit logs.

Three steps from config to production agent

Do I need an orchestrator?

No. Managed Agents replaces the pipeline entirely. You configure system prompts, models, call flows, and regions in the dashboard, the Execution layer handles routing, failover, and optimization underneath.

How do I connect SLNG Agent Builder to my systems?

Telephony comes in via SIP - Twilio, Telnyx, or your own trunk. Your CRM, ticketing system, or knowledge base connects through tool integrations via API. Configure, connect, ship. No pipeline code.

Does my voice AI data stay in-region?

Yes. Audio processed in a region stays in that region. Every call is logged with region, provider, model, and timestamp. You swap your base URL to the region of your choice.

Is SLNG compliant with GDPR?

GDPR compliant. ISO 27001 and SOC 2 Type II certified. HIPAA compliant. Details at trust.slng.ai.

How do I select a region?

One header: X-Region: ap-south-1. Add it to any API call. Same endpoint, same models, different physical location. No DNS changes, no separate deployments.

Which models are supported?

30+ models across STT, TTS, and LLM. Providers include Deepgram Nova 3, ElevenLabs, Cartesia Sonic, Soniox, Rime Arcana, Sarvam, and Whisper. Models are available as SLNG Hosted, SLNG Proxied, or BYOK. Full catalog at docs.slng.ai/models.
