A SIP and IAX / IAX2 phone utility especially designed for users who need to perform video calls, using any VoIP provider or PBX with ease


Review by Cristina Jitaru on January 30, 2014

Zoiper is a reliable and effective piece of software whose main purpose is to help users perform voice and video calls with their friends, family, colleagues and business partners. Unlike other programs such as Skype, the program allows you to use any VoIP provider or PBX you want.

When you launch Zoiper for the first time, the application requires you to configure the speakers, the microphone and the camera, then make sure that they work properly. After that, you need to create a new SIP, IAX or XMPP account by specifying the right credentials such as username, password and domain.

The main window of the application is intuitive and very easy to work with. Its multi-tabbed interface enables you to manage and organize all the available contacts, view all the call logs and change the status to ‘Online’, ‘Invisible’, ‘Away’ or ‘Be right back’.

By accessing the Contacts tab, you are able to manually add other contacts, import from another source or find contacts that are already available in the program. Zoiper provides you with useful wizards that will guide you through all the necessary steps. You are able to specify details such as name, country, city and phone number, as well as assign a personalized image for each contact.

The Dialpad tab displays a virtual phone machine with buttons and controls from where you can dial any number you want. Additionally, you can start chatting or perform a video call.

One important feature is that Zoiper integrates within various mail clients such as Outlook, Lotus Organizer, Thunderbird and even browsers, here referring to Internet Explorer, Firefox or Chrome so you can call any contact you want.

To wrap it up, Zoiper proves to be an effective and steady solution when it comes to performing various video calls effortlessly, as well as managing all the contacts, sending fax messages and start chatting with your friends.

In case the account wizard is unable to automatically configure your account, this could be due to a variety of reasons.

Most common reasons are:

  • The server hostname does not exist or is incorrect.
  • The username or password is incorrect.
  • The server is not responding or a firewall is blocking the access.
  • The account needs additional configuration to register
