What does tariff log show?
May be it's hack.

What type of lines do you have?

Could be system is not getting disconnect signal if caller hang up at disa

thanks for help, our line are analogue lines, and yes some of these lines do not support disconnect signal but it should disconnect after not entering any number or after enterning number if the time of queue is over!
btw what can i do if some line don`t have cpc detectio support?

sir_think_alot, I have a little idea.
Sir, do the following as into attached file.
ICD group №601 consists extensions whos answers the call after DISA.

Analog lines doesn't have start stop bits when incoming call answered by DISA and caller disconnect call in middle then call keeps ringing
until its ring timer.you cant do anything with analog lines in such case you need PRI.

second check whether your lines are crossed with other lines some time crossed line ringing voltage passes to other line and creates false call.
