PXO+

Softphones are applications designed to mimic how a handheld device should work. You might wonder who would choose a softphone over communication-oriented apps like skype, Zoom, etc. The answer is security, and the protocols involved in delivering a worry-free conversation in order to accommodate business talk or sensitive information sharing.

PXO+ is a neat softphone that employs a handful of communications protocols and codecs, so you can make calls, use fax, and record conversations with ease.

Softphones usually come with a phone-shaped UI, PXO+ sticking to the same rule. It might not be the slickest of layouts, but if you are not into aesthetics too much, it won't matter.

Use the mouse to dial numbers manually, or click on the "dir" button to access the phone book. In there, one can add contacts along with their numbers for work, fax, cellphone, or any other example. Speed dialing is a plus for anyone, just take advantage of it.

The app seems to be built to work with the RTC and VoIP protocols. For peer-to-peer connection, SIP and SIPS are being deployed. To ensure a secure environment, the SRT (Secure Real-time Transport) protocols are in place.

To summarize, PXO+ is a tiny softphone aimed at businesses and users looking for more secure and out-of-sight ways of communication.
