why is my wifi indicator got a telephone under it

Okay so basically on samsung galaxy s5 5.0.2 update and on the norification bar where the wifi indictator is there is now a wifi icon and then next to it another wifi icon but with a telepton underneath the icon. Why is that?
Has any one else seen this?
Thanks

Welcome to Android Central.

I'm guessing that it may indicate Wi-Fi calling and texting, useful if your mobile data signal is down.
