office phone constantly ringing

[Anonymous]

Good afternoon!
It seems that I have the following problem in my office: there is an automatic redial to our PBX (we have several lines) and the phone is constantly busy, you can call, but very rarely, we lose customers.
With what it can be connected?

Good afternoon, Leva!
perhaps someone has set up an automatic redial on your phone. This can be done, for example, using the skype killer program

A special device, the so-called telephone spammer, has been developed.
The numbers are entered into it, to which he will call ... and there is a ringing.
It’s almost impossible to determine where the call comes from. Such a thing costs around 15 thousand rubles.
