<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">i am not sure if its a good idea to only look at the _condition and stop playtones.
AFAIK chan->tech->indicate looks mostly on the visible_indication which is here set to 0 if _condition is < 0.
this could means chan->tech->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->tech->indicate function. maybe you can see some difference there between condition and visible_indication.

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Thank for review.
Neither channel driver look to visible_indication:
may@vl:~/asterisk/x/original/trunk> find channels/ -name '*.[ch]' | xargs grep visible_indication
may@vl:~/asterisk/x/original/trunk>
ast_playtones_stop just call ast_deactivate_generator that remove generator only if exists so
there will not problem even if it will called twice:
----
void ast_deactivate_generator(struct ast_channel *chan)
{
ast_channel_lock(chan);
if (chan->generatordata) {
....
}
ast_channel_unlock(chan);
----

If channel->tech->indicate return zero then processing go to indicate_cleanup before processing negative condition arg, it's bug
because we must stop tone generator if condition arg is negative independent of returned from tech->indicate value.
The patch call ast_stop_playtones before processing indicate return value.</pre>
