Anyone interested in free Skype calls?

Question

SIP

Due to the fact that the "Links" section was closed. I'll ask a question.
Anyone interested in free calls from Skype
to telephone numbers in Moscow, St. Petersburg, Novosibirsk, London!
Those who are not interested in this issue can pass by.
And who is interested, can look at the link .
This find, in my opinion, is interesting, I don’t know how long the “freebie” will last.
But while it works...
