How to Attribute Phone Calls to Your CTV Campaigns With CallRail x Vibe

Guest post by CallRail

Every CTV advertiser wants to know the same thing: which campaigns are actually driving revenue? Streaming ads reach the right households, regularly exceed 95% completion rates, and build real demand. But when a viewer finally acts, it usually happens offline — as a phone call.

Marketers have traditionally struggled to connect TV advertising to revenue. A business running a late-night TV spot decades ago knew it worked because the phone started ringing the next morning, but there was never a way to connect that ad to the phone call itself. Streaming TV has finally made that possible.

Unlike linear TV, where you buy a broad time slot and pay to reach an entire market, CTV lets you target precise audiences and geographies — like homeowners in a specific ZIP code or income bracket, for example. That household-level precision is also what makes the measurement problem solvable.

What is the CTV attribution gap?

Imagine a marketing agency runs a connected TV campaign on behalf of a client. Alongside their streaming ads, they also run paid social, local service ads, and paid search. A few weeks in, the client sees an influx of phone calls. The problem is that the reporting shows that paid search and social media are driving conversions while the CTV campaign just shows a high volume of impressions. So the client draws the only conclusion the data supports: the streaming campaign isn’t working, and the budget would be better spent on Google Search instead.

What that surface-level reporting fails to capture is that your CTV campaigns are generating bottom-of-funnel demand. The CTV campaign may be exactly what’s generating those calls but has no way to prove it.

CallRail is a lead engagement platform that can track your inbound phone calls and texts as CTV conversions. The Vibe x CallRail integration uses household IP matching to connect the impression to the call. When a streaming TV ad is served to a household, it’s delivered to a specific household IP address. When a call comes in, CallRail resolves the caller’s phone number to a household and matches it against the log of households that received the impression. The same household-level matching that makes CTV targeting accurate in the first place is what CallRail uses to close the loop on measurement. More than 1,900 Vibe advertisers, across legal, home services, automotive, healthcare, and financial services, are already using it.

The same tracking works across your other channels. Dynamic number insertion (DNI) shows each website visitor a unique phone number tied to their session, revealing which marketing campaign caused them to pick up the phone — whether that was a Facebook ad, a display ad, or a Google search. And when no one can pick up, CallRail’s Voice Assist handles the call so after-hours leads don’t go to voicemail.

Why this matters for CTV advertisers

Call-based businesses have the most to gain from closing this gap.

Phone calls are your highest-intent channel: Someone who picks up the phone has high buying intent, and they’ve given you consent to speak with them directly.
CTV competes for the same dollars as the rest of your marketing budget: Without data to back it up, even a channel that’s driving revenue can lose the argument for more spend.
Most calls don’t come in right away: Most attribution windows only look an hour or so past the ad. However, Vibe platform data from the last 90 days shows that nearly half of all CTV-attributed leads from CallRail customers came within 24 hours of the impression, while only 5 percent arrived within the first hour.

Why CallRail and Vibe work better together

Once your CTV campaigns are correctly attributed to the phone calls they generate, the benefit goes beyond knowing which campaign gets credit — it’s knowing whether that campaign is driving quality conversations for your business. Which streaming campaign drove a six-minute conversation with a qualified buyer? Which one drove someone to call and become a client on the spot? With the Vibe x CallRail integration, CTV can finally be measured the same way as search and paid social with metrics that actually matter: cost per qualified call, call duration, and conversion rate from call to customer.

The result is more high-quality leads, smarter decisions about where to invest, and follow-up that starts with context instead of guesswork.

Stop operating in the dark. Get a complete picture of your CTV campaigns’ impact with the native Vibe x CallRail integration.
