Skype

One of the most popular cross-platform applications for IP telephony, allowing users to communicate with people worldwide. It supports high-quality voice and video calls, chat messaging, and video messages. The program itself is completely free—you only pay for your internet connection. To get started, you need to register and create an account. After that, any service user on any platform can contact you and start unlimited communication. By adding friends to your address book, you can always see their online status or if they are away. Skype also allows file transfers, group conversations (conferences), and the use of emojis, animated stickers, and fun video clips in messages. Several additional paid services are available, such as calling regular (landline or mobile) phones, accessing WiFi networks, sending SMS messages, and more. Skype also enables communication with users who do not have an account. Simply create a new conversation and send a link to friends via email or another instant messaging service. By accessing the link in any browser, users can chat and make calls with a specific person or even a group of people. Regarding security, the developers guarantee maximum privacy and confidentiality: all communication between users is encrypted and protected from interception. Key features of the application include unlimited calls regardless of time or distance, excellent sound quality, status display of friends (online, away, do not disturb, etc.), file, photo, and video sharing, a wide range of emojis and GIFs for expressive communication, encrypted conversations for maximum security, and compatibility with all firewalls and routers without additional setup.
