AFAIK chan-&gt;tech-&gt;indicate looks mostly on the visible_indication which is here set to 0 if _condition is &lt; 0.

this could means chan-&gt;tech-&gt;indicate is doing everything fine with indication 0 but you maybe do stop_playtones twice and i dont know if this could lead to other problems.

if this is a reproduceable problem you should try to see what happens in the used chan-&gt;tech-&gt;indicate function. maybe you can see some difference there between condition and visible_indication.

If channel-&gt;tech-&gt;indicate return zero then processing go to indicate_cleanup before processing negative condition arg, it&#39;s bug
because we must stop tone generator if condition arg is negative independent of returned from tech-&gt;indicate value.

The patch call ast_stop_playtones before processing indicate return value.</pre>
