[Freeswitch-users] conference pin issue

[George Niculae]

Hi All,

I noticed that in a pin protected conference scenario, if the user inputs
more digits than the length of the correct one the remaining digits are
accounted for next retry - e.g. if the conf pin is 1234 and user enter 12345
then 5 will be used as first digit in 2nd retry. Extension is configured as:

  <extension name="5678">
    <condition field="destination_number" expression="^uuu$">
      <action application="set" data="supplied_pin=${sip_h_X-ConfPin}"/>
      <action application="export" data="supplied_pin=${sip_h_X-ConfPin}"/>
      <action application="bridge" data="loopback/app=conference:uuu at 5678
+1234"/>
    </condition>
  </extension>

I attached a patch for mod_conference that checks pin buffer to be 0 before
starting to collect digits again and reset it if > 0. I also modified the
code to play "please enter the conference access number" prompt just first
time and only "the passcode you entered is not correct, please try again" on
subsequent retries.

Please review the patch and let me know your comments.

Thanks,
George
