Why We Built Live Call Routing the Lean Way

When email is not enough, you need a human on the phone. Live Call Routing should not require a sales cycle or telephony markup. Here is how All Quiet built it the lean way.

Why We Built Live Call Routing the Lean Way

Most on-call setups run on automated alerts, and that covers the majority of pages. It stops being enough when a production database goes down at 3:00 AM, or when a high-priority customer is in a full outage. A support email or chat message does not always cut it. Sometimes you need a human on the phone.

If you have looked at Live Call Routing in other incident tools, voice often sits behind enterprise pricing or a reseller markup. We wanted the opposite: a straight path from caller to on-call engineer, without a sales call in the middle.

The All Quiet approach to voice

  • No enterprise gating: Live Call Routing is available on our Pro plan. No "call for quote" required.
  • Bring Your Own Provider (BYOP): Connect your existing Twilio account via API. You keep your numbers and your provider relationship.
  • Zero markup: You pay Twilio directly. We do not take a cut or markup your telephony rates.
  • Dev-first config: Manage your Interactive Voice Response (IVR) via our UI or via Terraform for infrastructure-as-code teams.

The "contact sales for pricing" wall

Setting up a live hotline or an IVR menu with some VC-backed competitors usually ends the same way: "Contact Sales for Enterprise Pricing."

For those vendors, voice routing is a lever to push smaller teams into annual contracts and, often, to resell telephony at a margin. You end up paying a middleman for infrastructure you could run yourself.

We are revenue-funded, not growth-at-all-costs. If you need a duty phone for your infrastructure, you should not need a procurement cycle to get one.

Why we chose Bring Your Own Provider (BYOP)

When we designed call routing, we had two options:

  1. Resell phone numbers and charge a premium on every minute.
  2. Build routing logic that plugs into the VoIP stack you already run.

We chose the second. All Quiet integrates with Twilio so you wire in your API keys, map your virtual on-call numbers, and keep paying your provider's rates.

  • Zero telephony markup: You pay Twilio directly. We handle inbound call routing and on-call logic; we do not touch your minute billing.
  • Data stays with you: Call recordings and provider-side logs remain in your Twilio account. We run the routing and incident creation so the right engineer gets the ring, without copying your voice data into a separate silo.

SRE-first design: UI-friendly, Terraform-ready

Enterprise phone systems are built for call centers. Menus go deep, labels use telecom jargon, and the admin UI assumes a dedicated phone team. We built for DevOps and SRE workflows instead.

1. IVRs should not require a certification

Our visual builder lets you map Press 1 to Overnight Squad in a few clicks. The point is to set up a bridge during a mid-level incident without opening a vendor manual. Less cognitive load when the pager is already loud.

2. Infrastructure as Code (yes, even for your phone tree)

A good UI helps for quick changes. Most teams still want version control, review, and repeatability for anything that affects production response paths.

All Quiet is API-first and Terraform-ready. You can manage Live Call Routing the same way you manage AWS or GCP resources. If you already treat on-call configuration as code, your phone tree can follow the same workflow, including escalation paths when the first responder does not answer.

Available for everyone, not just enterprise

We did not put Live Call Routing behind an Enterprise tier. It ships on Pro because a five-person startup handling a customer outage deserves the same voice path as a larger org.

All Quiet is a lean incident platform for the people who actually run the systems. Without a massive sales org to feed, we can ship features that solve on-call problems instead of features that inflate contract size.
