Digital attribution is easy when everything happens online. You can track clicks, impressions, form fills, and page views without breaking a sweat. But what about leads that call your business after seeing a billboard or hearing a radio ad? That’s where CallRail truly shines.
CallRail fills the offline attribution gap by tracking phone leads and mapping them back to the original source. Whether a prospect comes from Google Ads, direct mail, or a printed flyer, CallRail lets you see the full path from interest to conversion. It transforms phone activity into real, measurable return on investment.
Track Phone Leads from Online and Offline Sources
With CallRail, you can assign unique phone numbers to each marketing campaign, whether it’s digital or offline. For example, you can create one number for your Google Ads campaigns, one for a postcard mailer, and another for your billboard. When someone calls, you instantly know which channel brought them in.

The system captures detailed caller data, including call duration, location, first-time vs. repeat caller status, and source attribution. That means you’re no longer guessing which ad drove that call; you can see it clearly in your CallRail dashboard.
Multi-Touch Attribution and Assisted Conversions
Customers rarely take action after one touchpoint. They might see your flyer, then Google your brand a few days later, and finally call after reading your reviews. CallRail’s multi-touch attribution enables you to track the entire customer journey. You’ll see which ads or sources played a role in driving the conversion, even if they weren’t the final trigger.
This provides a clearer understanding of your entire sales funnel. You can stop overvaluing last-click interactions and start giving proper credit to every campaign that influences buyer behavior.
Link Calls to Revenue with CRM Integration

CallRail makes it easy to connect your phone leads to actual sales using CRM integrations. Whether you’re using HubSpot, Salesforce, Pipedrive, or another platform, CallRail can push call data into your CRM in real time. When your sales team closes a deal, you’ll be able to trace it all the way back to the ad that drove the initial call.
This level of insight transforms CallRail into more than just a call tracking tool. It becomes a complete ROI attribution engine, helping you prioritize high-performing campaigns and eliminate budget waste.
Real-World Example: From Flyer to Booked Job

Let’s walk through a practical scenario. A homeowner sees your print flyer advertising a plumbing service. The flyer includes a CallRail tracking number. A few days later, they search your business on Google, click your website, and the same number appears thanks to dynamic number insertion.
They call your office, speak with a rep, and the conversation is recorded and scored. Later, your team schedules the service. That deal gets logged in your CRM and is attributed to the flyer campaign.
The full lead journey looks like this:
Print flyer → Google search → website visit → dynamic phone number → call → appointment booked → CRM deal closed
CallRail tracks every step, helping you prove that offline marketing still works, especially when paired with smart tracking.
