Make international calls cheaper and right from your browser - Voixcall.com is here

 


Voixcall.com


VoixCall is a browser-based international calling service that launched on May 6, 2025, offering high-quality voice calls to any phone number worldwide without requiring downloads or subscriptions, and operating on a simple pay-as-you-go credit system(Product Hunt). Users simply sign up with an email address, add credits in their preferred currency, and dial directly from the web interface, benefiting from WebRTC-powered, end-to-end encrypted connections that work in any modern browser(voixcall.com, voixcall.com).

How It Works

VoixCall leverages industry-standard WebRTC technology to transmit voice data directly from your browser to the public telephone network, eliminating the need for downloads or plugins(voixcall.com, VoiceSpin). Once you’ve created an account, you add credits and enter any international number; VoixCall’s global SIP backbone then routes your call with HD-grade audio and minimal latency(voixcall.com). Because everything runs in-browser, there’s no software installation, no background services, and no risk of VoIP ports being blocked by carriers or firewalls(Medium).

Key Features

  • Global Reach: Call any country without restrictions—landlines, mobile phones, government or institutional numbers alike(voixcall.com).

  • Flexible Currency Support: Choose from multiple currencies (USD, INR, EUR, etc.) and see real-time exchange rates when adding credits(voixcall.com).

  • Secure & Private: All calls are encrypted end-to-end, and VoixCall does not share call metadata with third parties beyond telecom providers and payment processors(voixcall.com).

VoixCall’s pricing is fully transparent and varies by destination and duration:

  • Per-minute rate: From $0.02/minute (e.g., calls to major destinations start as low as $0.02/min) up to $0.10 total per call for short connections(voixcall.com).

  • Credit Packages: Purchase credits in increments of your choice—add exactly what you need, with no minimums and no hidden fees(voixcall.com).

  • Currency Selection: Pay in USD, INR, EUR, and other supported currencies, with live exchange-rate calculations shown at purchase time(voixcall.com).

Policies & Support

  • Refund Policy: Eligible requests are reviewed within five business days; approval depends on the nature of the issue and supporting documentation(voixcall.com).

  • Terms of Service: Users agree to a credit-based usage model and acknowledge that call quality may vary based on internet conditions and destination networks(voixcall.com).

  • Customer Assistance: For questions or technical support, VoixCall offers email support via the “Contact” page on their site(voixcall.com).

A BEGINNERS GUIDE TO HACKING UNIX

 


*************  *       A BEGINNERS GUIDE TO:        *  *          H A C K I N G             *  *                                    *  *                U N I X             *  *                                    *  *       *  * **


   IN THE FOLLOWING FILE, ALL REFERENCES  MADE TO THE NAME UNIX, MAY ALSO BE  SUBSTITUTED TO THE XENIX OPERATING  SYSTEM.    BRIEF HISTORY:  BACK IN THE EARLY  SIXTIES, DURING THE DEVELOPMENT OF  THIRD GENERATION COMPUTERS AT MIT,  A GROUP OF PROGRAMMERS STUDYING THE  POTENTIAL OF COMPUTERS, DISCOVERED  THEIR ABILITY OF PERFORMING TWO OR  MORE TASKS SIMULTANEOUSLY.  BELL  LABS, TAKING NOTICE OF THIS DISCOVERY,  PROVIDED FUNDS FOR THEIR DEVELOPMENTAL  SCIENTISTS TO INVESTIGATE INTO THIS  NEW FRONTIER.  AFTER ABOUT 2 YEARS OF  DEVELOPMENTAL RESEARCH, THEY PRODUCED  AN OPERATING SYSTEM THEY CANLMD "UNIX".    SIXTIES TO CURRENT:  DURING THIS TIME  BELL SYSTEMS INSTALLED THE UNIX SYSTEM  TO PROVIDE THEIR COMPUTER OPERATORS  WITH THE ABILITY TO MULTITASK SO THAT  THEY COULD BECOME MORE PRODUCTIVE,  AND EFFICIENT.  ONE OF THE SYSTEMS THEY PUT ON THE UNIX SYSTEM WAS CALLED  "ELMOS". THROUGH ELMOS MANY TASKS (I.E. BILLING,AND INSTALLATION RECORDS) COULD  BE DONE BY MANY PEOPLE USING THE SAME  MAINFRAME.    NOTE: COSMOS IS ACCESSED THROUGH THE  ELMOS SYSTEM.    CURRENT:  TODAY, WITH THE DEVELOPMENT  OF MICRO COMPUTERS, SUCH MULTITASKING  CAN BE ACHIEVED BY A SCALED DOWN  VERSION OF UNIX (BUT JUST AS  POWERFUL).  MICROSOFT,SEEING THIS  DEVELOPMENT, OPTED TO DEVELOP THEIR OWN  UNIX LIKE SYSTEM FOR THE IBM LINE OF  PC/XT'S.  THEIR RESULT THEY CALLED  XENIX (PRONOUNCED ZEE-NICKS).  BOTH  UNIX AND XENIX CAN BE EASILY INSTALLED
ON IBM PC'S AND OFFER THE SAME FUNCTION
(JUST 2 DIFFERENT VENDORS).

NOTE: DUE TO THE MANY DIFFERENT
VERSIONS OF UNIX (BERKLEY UNIX,
BELL SYSTEM III, AND SYSTEM V
THE MOST POPULAR) MANY COMMANDS
FOLLOWING MAY/MAY NOT WORK. I HAVE
WRITTEN THEM IN SYSTEM V ROUTINES.
UNIX/XENIX OPERATING SYSTEMS WILL
BE CONSIDERED IDENTICAL SYSTEMS BELOW.

HOW TO TELL IF/IF NOT YOU ARE ON A
UNIX SYSTEM:  UNIX SYSTEMS ARE QUITE
COMMON SYSTEMS ACROSS THE COUNTRY.
THEIR SECURITY APPEARS AS SUCH:

LOGIN;     (OR LOGIN;)
PASSWORD:

WHEN HACKING ON A UNIX SYSTEM IT IS
BEST TO USE LOWERCASE BECAUSE THE UNIX
SYSTEM COMMANDS ARE ALL DONE IN LOWER-
CASE.
LOGIN; IS A 1-8 CHARACTER FIELD. IT IS
USUALLY THE NAME (I.E. JOE OR FRED)
OF THE USER, OR INITIALS (I.E. J.JONES
OR F.WILSON).  HINTS FOR LOGIN NAMES
CAN BE FOUND TRASHING THE LOCATION OF
THE DIAL-UP (USE YOUR CN/A TO FIND
WHERE THE COMPUTER IS).
PASSWORD: IS A 1-8 CHARACTER PASSWORD
ASSIGNED BY THE SYSOP OR CHOSEN BY THE
USER.
