[Freeswitch-users] session.recordFile create empy wav in whileloop

[Jason Moran]

I thought you could stop the record via an action in your callback
function?
For example if you used this format:
session.recordFile(fileName, callbackFunction, "", maxreclen,
silencethreshold, silencehits);

Let's say you passed in "onRecordDTMF" as your callbackFunction:
session.recordFile("/dev/shm/"+rd+".wav", onRecordDTMF, "", 10, 500, 3);

function onRecordDTMF(session, type, digits, arg)
{
    if (digits.digit == "#") {
        return false;
    }
    else {
        return true;
    }
}

The recording would end in 2 possible ways: Let it have the silence
timeout or allow a force recording end with the "#" DTMF symbol.  Your
recording message could indicate to hit the "#" to end recording (or
allow the silence to stop it).

whileloop

Hi Steve,
Thanx for helping me,
the call is established and the loop can be re-run and re-run. but the
new audio file that is created is empty.
i have the same issue if i use session.execute("record",
"/dev/shm/"+rd+".wav 10 150");

unfortunately there is no function to stop the record.

If you can help me I would be very thankful

Daniel
