The website is set to offer two-minute calls about the duration of a tweet without any cost, where members can talk for the first time without making their phone numbers public.
Users would be, however, required to first join online telephony site Jajah and call a follower, with a tweet "@call @twittername" that will make both phones ring.
"You tweet (family or friends), when you've got something really quick to say and you make a quick two-minute free call," News.com.au quoted Paul Naphtali, Jajah's Melbourne-based head of marketing, as saying.
"For dating, you approve each other and then you can call them," Naphtali added.
Naphtali revealed stalkers could easily be taken care of since only people whom users follow could call them.
And if the calls get frantic, then people can cut the link by unfollowing them.
