Zoiperfor Mac

Zoiper is a telephony application that offers basic and advanced VoIP functionalities at a low cost. Unlike other popular VoIP apps, Zoiper Free supports more advanced telephony standards such as T.38 Fax over IP and Asterisk and SIP-capable IP-based communication systems. It boasts a sleek interface and provides features like a contacts book, call history, videoconferencing, call forwarding, and the ability to manage multiple accounts.

Zoiper integrates into Outlook and supports high-quality voice codecs such as GSM, Speex, ILBC, or 711th/u. The developers claim that this results in one of the highest quality audio experiences available on a VoIP app, reducing the annoying echo that often plagues other apps. However, it becomes difficult to discern whether any decline in voice or call quality is due to Zoiper or the VoIP client being used.

Overall, Zoiper is an interesting product that could potentially improve call quality. However, it may be a bit of a hassle to use when compared to other VoIP apps like Skype, which offer similar voice quality and user friendliness.
