How to make busy beeps for incoming (Asterisk)?

Question

Asterisk

When the operator speaks on the phone, the one who calls him hears not busy beeps, but one very short and immediately break.
That is, it is not clear whether it is busy or the phone does not work.
Terminate call is busy.
I do Zapateller, it sounds, but it's a little different, you just need short beeps.
What is the reason?

Answer 1

Processing in a context like:

exten => _X.,n,Dial(${exten},${RINGTIME},${DIALOPTIONS})  ; Ring the interface, Ringtime seconds maximum
exten => _X.,n,Goto(stdexten-${DIALSTATUS},1)  ; Jump based on status (NOANSWER,BUSY,CHANUNAVAIL,CONGESTION,ANSWER)
exten => stdexten-NOANSWER,1,Play("record/noanswer")
exten => stdexten-NOANSWER,n,Return()
exten => stdexten-BUSY,1,Play("record/busy")
exten => stdexten-BUSY,n,Return()
exten => stdexten-CHANUNAVAIL,1,Play("record/canal-nedostupen")
exten => stdexten-CHANUNAVAIL,n,Return()
exten => stdexten-BUSY,1,Play("record/busy")
exten => stdexten-BUSY,n,Return()
exten => stdexten-CONGESTION,1,Play("record/drugaya-oshibka")
exten => stdexten-CONGESTION,n,Return()
exten => stdexten-ANSWER ...............

Will play different message options for different event

Answer 2

If this happens only from an external network, then most likely the problem is not with you. Write in more detail who is calling whom and show your log from the Asterisk console.
