Our favorite SIP VoIP app for business

Before we go ahead and tell you about our recommended VoIP apps, it’s important that we clarify one thing: Is a VoIP app appropriate for business use? Our answer is yes, and we base that on long and intensive testing of the most important apps out there, and on our business clients’ very positive feedback.

Many business owners or managers might think that this is only a solution for small businesses, when it can do a lot more than just reduce your costs. If you don’t have Internet cabling throughout the office, you have employees travelling or working from home occasionally, sales people or other “road warriors” who are out of the office all the time or just want to avoid buying hardware, make sure you do take into consideration using your business phone system with a VoIP app.

ZoiPer is a VoIP client (or Softphone) available on almost any platform you can think of: Windows, Mac and Linux OS for computers or laptops and Android, iOS and Windows Phone 8 for Smartphones, and even offers a web-based version.

We like it because:

  • The software is user-friendly, very easy to install
  • Call quality is superior thanks to various settings such as echo cancellation, Adaptive Jitter Buffer, Packet Loss Concealment and Noise reduction.
  • Unlike other apps we’ve tested that were disconnecting from time to time, it does not lose registration when running in the background
  • It integrates with various business applications, such as Outlook, Thunderbird, Goldmine, Lotus Organizer and any TAPI-compatible CRM system
  • Offers many business features even in its free version
  • Provides Instant Messaging (IM) and presence, making it easy to communicate within a company

Whether you go with the Free or Biz solutions (paid), we are sure that the liberty provided by a softphone will win you over. Of course, we cannot make a general recommendation or vouch for its quality with all VoIP providers and under all network conditions. Your VoIP quality will depend mainly on your Hosted PBX provider’s service quality; also, be reminded that in order to use a Softphone application with your Hosted PBX account you will require a stable Internet connection; this can be a wired connection for your laptop/ computer, or Wi-Fi / data plan for your mobile.
