[asterisk-users] AGI GET DATA behavior

[Hoggins!]

Hello all,

I have a strange problem with a very simple AGI script, using the GET
DATA command.

When using this command, Asterisk often returns 0 as a result after a
"GET DATA beep 5000" command, without even waiting for input from the
calling party.
It is quite random : sometimes Asterisk behaves exactly as documented,
and sometimes it gives "200 result=0" without any reason.

Do you have an idea of what might be happening ? I'm using version 11.6.0.

    Hoggins!
