It was back in August last year when Google revealed that its video calling app Duo will soon start offering audio-only calling as a feature. For those who have been waiting for the functionality all this while, you'll be glad to know that the roll out has finally begun.
"This feature will be available starting today first in Brazil, and we'll be rolling it out to users around the world in the coming days," the Mountain View, California-based company said in a blog post today.
In case you aren't aware, Duo is already optimized for poor networks, capable of even switching to audio calling if connectivity is weak. However, now audio-calling will be there as a separate feature as well.
