How to reset outgoing when the status is "busy"?

Question

Asterisk

Comrades,
Help with editing the code, I can’t figure out how to reset an outgoing call if the line “where” they call (or call) is busy. The situation is as follows: There are several lines, I dial a mobile number, I call, the first line in the list is taken, the call comes from her name. If I reset the call on my mobile (like I'm busy), then the asterisk automatically dials from the second free outgoing line, and again I have to reset it, and so on until the entire enumeration is completed.
How to reset an outgoing call if the subscriber dropped the incoming one?

Full code under the spoiler.
As I understand it, you need to delve into the section:

[outgoing]
exten => _XXX.,1,Macro(recording,${CALLERID(num)},${EXTEN})
exten => _XXX.,n,Gosub(trunk_check,s,1(${EXTEN}))

Here I just did a search of free lines so that people could call, but there is no call reset when there is a "beat" that the line is busy.

Answer 1

Check call status when finished. But with this scheme, you still need to check the line before starting the call.

// вот простой пример на AEL))

_XXX. => {
        Noop(---------CALL-OUT-AEL--------);
        Set(lineList=213135;213136)
        while (${LEN(${lineList})} > 0) {
                Set(OUT_LINE=${CUT(lineList,;,1)});
                Set(__lineList=${CUT(lineList,;,2-)});
                if("${DEVICE_STATE(SIP/${OUT_LINE})}"="NOT_INUSE") {
                        Dial(SIP/${EXTEN}@${OUT_LINE},45,T);
                        if("${DIALSTATUS}"="ANSWER") {HangUp;}
                        if("${DIALSTATUS}"="BUSY") {HangUp;}
                }
        }
        HangUp;
        }
};
