Telnyx already gives you tier-1 carrier infrastructure, programmable voice, and a built-in path to LLM-powered assistants on Telnyx Inference. ECP adds the institutional layer your CISO will ask for next: prompt versioning, per-assistant policy, tool-call RBAC, and an immutable audit trail for every call that runs across your Telnyx number.
Telnyx customers don't tolerate flaky infrastructure — that's why they're on Telnyx. The same standard now applies to AI behavior. When a Voice AI assistant on a Telnyx number quotes a price it shouldn't, commits to a refund policy that doesn't exist, or drifts after a model update, your number — and your brand — is the one on the call. Telnyx delivers the carrier reliability. Elacity ECP delivers the same level of rigor for the instructions the assistant ran on.
Telnyx owns the network and the runtime. ECP owns the governance surface around it.

Live Phone CallEvery system prompt, instruction, voice config, and assistant template — versioned, diff'd, attributed. Roll back any Telnyx Voice AI assistant to any prior state. End the 'who edited the prompt' archaeology.
Define what each Telnyx assistant can say, ask, quote, or commit to. ECP enforces the rules at configuration time. Guardrails before the call, not after the support escalation.
Telnyx Voice AI can call out to your CRM, billing, scheduling, internal services. ECP applies role-based access control and produces a signed log of every tool invocation — per assistant, per call.
Running multiple Telnyx assistants per business line? ECP baselines them and surfaces behavioral variance — across deploys, model swaps on Telnyx Inference, and prompt edits — before drift turns into a regulatory event.
Per-call, ECP logs the exact prompt, model, voice, allowed tools, and policy state the Telnyx assistant was running with. The audit record sits next to Telnyx's call recording and transcript — and it survives a HIPAA, PCI, or SOC 2 review.
Telnyx customers expect five-nines from the network. ECP is built to match that posture — a control plane your platform team can put behind a Telnyx deployment without becoming the new single point of failure.
Telnyx already vertically integrated voice — owning the network, the runtime, and now the inference layer. The next vertical is governance: who decides what the assistant on a Telnyx number is allowed to say, who can change it, and who can prove what it did. ECP is that layer, and it doesn't require a re-platform.
Connect ECP to your Telnyx account via API.
Import your current Voice AI assistants and tool definitions.
Set baseline prompts, per-assistant policies, and tool RBAC.
Turn on drift monitoring and call-level audit capture.
Estimated setup: Less than 1 day to your first governance event
Elacity runs ECP internally across roughly 1,000 active agents — including voice assistants delivered over carrier networks. The same control plane we offer Telnyx customers, in production, today.
We get this question on every Telnyx call, so it's worth being explicit. ECP isn't a Telnyx competitor — it's a layer that makes Telnyx Voice AI defensible inside a regulated business.
Flat governance capability pricing. Not per agent. Not per call. Not per token.
No per-minute fee. No per-assistant tax. Telnyx scales however Telnyx scales — ECP stays flat.
Built for the regulated businesses running real numbers on real networks.
