This is not done by Asterisk, unless you have set you country code to one that uses that tone as ring back tone.

Thanks a lot David, let me explain the same in details actually while I dial the number a continue beep sound comes during the ring time, the moment customer answer the call we dont listen any beep this is happening only during the ring time.
I am not using any country code as doing local India calling through PRI only.

By country code, I mean tonezone.

What do you expect to here as ring back tone (the tone sent to the caller when the callee is being alerted)?

A quick check on indications.conf makes me think that no country uses a one second cycle, so I would suggest this is early media coming from the called network.

I suppose it could also be introduced by the calling network to indicate early media, to discourage its use for free calls.
