[Linphone-users] user manual of Linphone 3.5.0 for windows

[COU208]

Allo,

I am a new user of Linphone.

It seems to be a very good software with a lot of functionality.

Unfortunately, after I spent hours to find out documentation, I found only short doc outdated. 

Linphone 3.5.0 is able to do audio conferencing, multiple calls simultaneously and call transfer.

 Is it possible that somebody tell me how to do the last 3 actions precised. 

Thank you in advance
