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

One other thing to check - make sure you aren't having problems with
open file handles.  You might have to play around with issuing an
fd.close() at the appropriate time or else try incrementing the file
name (and other permutations) to ensure you aren't blocking yourself
from writing the same file.

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
