I think in mod_dptools.c in the play_and_get_digits_function there&#39;s some code that does:<div><br></div><div><div>    if (min_digits &lt;= 1) {</div><div>        min_digits = 1;</div><div>    }</div><div><br></div><div>
   My C is rusty and this may be irrelevant though!</div><div><br></div><div>-Gabe</div><div><div><br><div class="gmail_quote">On Mon, Jun 18, 2012 at 11:09 AM, Michael Collins <span dir="ltr">&lt;<a href="mailto:msc@freeswitch.org" target="_blank">msc@freeswitch.org</a>&gt;</span> wrote:<br>

The wiki just CAN&#39;T be wrong! ;) Actually, according to switch_ivr_play_say.c it looks like you can have a min_digits of &quot;0&quot;. Still, I&#39;d make the min digits &quot;1&quot; unless there&#39;s a compelling reason to want zero digits.<span class="HOEnZb"><font color="#888888"><br>
