Yoomba integrates into email applications, adding buttons next to contact details in all of the major webmails, including Microsoft Outlook and Outlook Express. These buttons provide users with one-click access to all their contacts using voice or instant messaging. Once activated, Yoomba seamlessly loads all email contacts, giving users instant access at a glance, in order of popularity. The top 20 people in each user's Yoomba contact list will be the top 20 people they most frequently email.
Elad Hemar, Co-founder and CEO of Yoomba said, "Before Yoomba, online communications offerings existed as part of closed networks. To communicate with friends, family or colleagues, users were required to join the network, register, create a new online identity, then search and add contacts one by one to each individual network. At Yoomba we are changing the way people communicate by providing the first open P2P network, putting consumers back in control. With Yoomba there is no registration, no need to create a new email address or a special number. You are no longer limited by the boundaries of an individual email or VoIP network. Yoomba has created email calling and email chat in the simplest way possible."
Yoomba is jointly headquartered in Tel Aviv, Israel and Silicon Valley in the USA.
Useless, all these plans. I have been using VoIPRaider.com and Nonoh.net since forever. Skype too is marketing hype. Even 50 paise for a US Canada call is pricey. Check out VoIPRaider.com
