PHILADELPHIA (KYW Newsradio) — Sick of robocalls? Comcast and T-Mobile have teamed up to combat the scourge.

The companies are now verifying whether calls between their networks are authentic - in other words, that the caller is a human.

It doesn't stop robocalls, but at least it makes it easier to spot and ignore them. 


Think of each phone line as having a security pass. Comcast and T-Mobile are checking that ID before passing the call onto you, and good ones will show up as "caller verified" on your screen. 

It's early days for this tech: it'll work first on 10 of T-Mobile's Android devices and only for calls across the two networks. 

Comcast and T-Mobile are working with other providers to get call verification up and running on more phones and networks.
