Call Tracking

Maximize the effectiveness of your online and offline advertising spend with the use of dedicated local or toll-free phone numbers.

It's Like Click Tracking

Call tracking is just like click tracking for online advertising. The key difference is that call tracking can be used effectively for offline ads as well.

Optimize Ad Spending

The main reason to use click tracking is to optimize ad spending. Call tracking does the same thing while allowing potential customers to call a toll-free or local phone number 24/7/365. 

Every Advertising Channel

Call tracking can be used to monitor online advertising campaigns on pay-per-click search engines like Bing Ads and Google Adwords.

Also, it can be used on TV, radio, billboard, and newspaper advertising as well.

Our customers can dedicate a phone number to each and every channel and easily determine the best and worst ROI fast.

Concurrent Callers

With Sigma Voice, your phone numbers can have a capacity of 100's of concurrent callers without sacrificing call quality. This way you won't lose any potential leads due to a busy signal.
