The old trade-off

Build it or give it away. Both lose.

When voice comes up on a portco's roadmap, the two familiar paths burn either years of engineering or a durable revenue stream.

Option one

Build it in-house.

Building a business VoIP phone system in-house takes years, even when you buy CPaaS infrastructure from vendors like Twilio. Plus then you're a regulated carrier owning E911, taxes, regulatory filings, hardware provisioning, and more.

Option two

Refer it away.

Referring customers to standalone phone systems like RingCentral or Dialpad gives away the revenue and the data. The calls, and everything in them, live in someone else's product, and the portco's customers spend more time in someone else's UI.

The third option

Embed it with DialStack.

Launch a fully branded Embedded Phone System and VoiceAI inside the portco's platform in days, not years. The brand, the revenue, and every call's data stay in the company you funded, and voice becomes high-margin revenue from day one.

What a portco gets

A complete phone system, wearing their brand.

Not an API project. A finished product surface the portco's customers use every day, deeply wired into the workflows that already live in the platform.

White-label portal

Call history, voicemail, and devices under the portco's brand.

Screen Pop

The matched customer record appears the moment the phone rings.

Click-to-Call

Any phone number in the portco's app becomes a button.

Activity Logging

Calls log themselves into the record automatically. No gaps.

AI Scheduling

Calls turn into booked appointments on the calendar.

VoiceAI, built in

Their AI or ours. Calls flow seamlessly either way.

VoiceAI is more powerful when it is native to the phone system: the portco's agent answers as a true extension, with full system privileges over calls, routing, and schedules from the first ring.

Incoming call Live user AI agent

Bring their own agent.

If the portco is already building a voice agent, it connects through the API and answers on real phone lines, with handoff to live users when the conversation needs one.

Explore BYO agent

Or start with the one built in.

It answers, schedules, and summarizes out of the box, so the portco ships AI calling without building an agent first.

What DialStack carries

Exit-ready compliance.

Regulated voice is a diligence problem when your portfolio company carries it, and a non-issue when DialStack does. We hold the regulatory load permanently, so the platform books the revenue and the data room stays clean.
