I think it’s extremely unlikely that your Skype calls are recorded … I’ll dive into a number of reasons I believe that to be the case.
You can contact any of your Gmail contacts, which are automatically imported to Google and Hangouts when you sign up.
If you are an Android user and are logged in as a Google user on your mobile device, your phone contacts are saved and synced with your Google account.
The technology is potentially recordable by the Skype servers.
It’s not confirmed, but we have to assume that it is possible.
This saves server bandwidth and decreases latency as participants stream directly to each other.
If P2P doesn't work due to client connections, streaming is done trough the RTMP server as usual.On the other hand, there is no clear statement on audio and video Skype calls.It could be end-to-end encryption, but there are indications that, particularly when routed through the Skype servers, the conversation could be visible or audible in unencrypted form.Unfortunately, many are paying a very steep price for that. On one hand, Microsoft is pretty clear that instant messaging traffic (text) is sent to its servers as well as the recipient.I don’t believe Skype (which is now owned by Microsoft) is recording your calls. If there’s a Skype-to-Skype connection, it may be encrypted end-to-end, but messages sent to the Skype servers are encrypted only en route, and arrive there unencrypted.While Whats App allows voice calling, conference audio calls and group video chats still don’t feature in one of the biggest messaging applications in the world.
