Skype alternative - cheaper and more reliable

Question

Skype

I'm tired of Skype - from a breath of freedom and independence from telecom operators, it has turned into a clumsy, expensive (at present) and not very high quality (people usually hear an echo, sometimes me) monster, forcing me with updates and changing the interface once a month, so that pensioners talking with their departed children need to get used to it again. Well, okay, there he is dear, along with Microsoft.
Who knows the alternatives? I call mainly to Russia and Europe. I would like for the following platforms - Linux, Win32, MacOS, iOS and Android. Thanks in advance.

Answer 1

Any SIP provider. I have a popular Sipnet, but recently there have been problems with calls, and I haven’t figured out which side of the fault is on yet.
SIP-clients sea for every taste for all platforms. On Mac OS X, I recommend Telephone.

Answer 2

sipnet.net
pctel.ru

Answer 3

I tried different sip providers + “phone” software, but I wouldn’t dare to recommend a single one, because. stability, skype shows itself in the best way, especially in calls within Russia (although more expensive)
, however, there is a solution where the sound quality is always good - this is a voip box (for example, linksys), into which the phone and ethernet are plugged, and then it calls like with a regular phone

Answer 4

XMPP aka Jabber
XMPP or Jabber (in fact, these words mean the same thing) is the name of an open decentralized network protocol that is used for instant messaging. It is designed as a server-client infrastructure with multiple servers all over the internet where anyone can get an account. These servers are typically connected to many clients on one side and to other Internet XMPP servers on the other side. Let's come up with a small example to explain how this works:
Romeo loves Juliet and wants to communicate with her through the Jabber network. He can write messages from his client (to which montague.net is connected) to his girlfriend, whose client is connected to the capulet.com server.
When he registered an account on the server, he chose the so-called JID (Jabber-Identifier). This JID works basically like an email address and is associated with the server name using the "@" symbol. An example for a valid Romeo JID is [email protected]
To communicate with other people, Romeo must add their JID to his contact list. They can be connected to the same server (for example, [email protected]), or they can come from a different server (for example, [email protected] or, of course, [email protected]).
Jabber Network Visualization
Jabber/XMPP, of course, supports many more services (eg, end-to-end message encryption, voice and video chat, group chat), which will be partly introduced later in the guide.
Two very large instant messaging providers run Jabber/XMPP on their servers in the background: Google Talk and facebook chat. Accounts on these systems can be used in the same way as regular Jabber accounts on Kopete. Details will be explained later or can be found on the websites of these providers.

Answer 5

I use 12voip. I call in Europe and sometimes in Ukraine. Cheap and convenient. Especially cool is that 90 days are given free of charge for calls to landlines. On a mobile phone, a client for android - MobileVoip works with 12voip

Any jabber, only no external calls.
