I am a happy user of IP-telephony, and specifically -
FreeCall . I will not dwell on all the numerous advantages of this service - I’ll dwell on the minuses: the native client is designed, essno, on
Windows . (by the way, it’s not difficult to install it in
Wine , but after 1C, it’s not a problem.)
Half an hour of polaziv in the Internet and not finding a clear step by step instructions on how to adapt the ip-phone from the above supplier to the harsh realities of
ubuntu decided to write his own:
')
First of all, we are convinced that Ubunta did not forget to drag with her and put
Ekiga . (If you suddenly forgot,
name @ host will help
: ~ $ sudo apt-get install ekiga ).
Next, run it. In answers to the questions of the wizard, you can not particularly strain, write anything. Anyway, then change everything :)

When dialing, the number should look something like the following:
sip: +7XXXXXXXXXXX@sip.voiparound.com But as practice has shown,
Ekiga can also substitute this excess into the dialed number. The main thing to dial a number in the international format.
If you suddenly have never heard anything about Aipy telephony and even more about Fricol, then you can find out about their tariffs
