Make Free Calls Using Firefox
With the Zoep Firefox extension, VoIPSter is bringing to the Internet the ability to make a phone call at the click of a button from an Internet browser.
With the Zoep Firefox plug-in, users can make free telephone calls and chat directly after installing the Firefox extension from http://www.zoep.com/firefox.
The Zoep extension provides users with a “seamless” in-the-flow experience, without having to switch between applications. By designing Zoep to mimic Firefox’s look and feel, extension makes initiating and receiving free calls using the OpenZoep VoIP platform simple.Users will now be able to communicate with any other VoIP user on the open source based OpenZoep platform, so in addition to being able to communicate with other Zoep users, they can also communicate with users on the Jabber platform including, sometime in the future, those using Google Talk.
Additional development plans for Zoep include voice-mail, SMS and an inbound phone number to accept incoming calls from landlines or mobile phones.
Written for the latest Firefox version 1.5, the Zoep extension is produced and maintained by developer Glaxstar Limited, developers of recently released Firefox extensions for clients Paypal and del.icio.us.
Ian Hayward, managing director and founder, Glaxstar, said, “Zoep is the perfect tool for smart people using Firefox who want to seamlessly integrate communication into their browsing experience with minimal fuss. It makes perfect sense to add telephone capabilities and a chat system into your browser, which is often your most used bit of software on the desktop. Now, you won’t have to stop browsing to answer the phone.”
