Well Mike,

I think for now I will use your suggestion ;)
and will update step by step my rfc2833 implementation...

Thanks

  Madovsky,

  I thing maybe don't understand what you are trying to do. Do you simply want to have a conference that requires the caller to enter a PIN? Or are you trying to send a caller to a conference that has a PIN but you want to send the PIN externally? 

  In case it's the latter you can do the following...
  Create a conference locked by a PIN. In the logs below I used conf 3300 at default and 1234 as the PIN. Then I called 3300 from user 1002:

  2010-12-14 00:00:21.518045 [NOTICE] switch_channel.c:784 New Channel sofia/internal/1002 at 10.15.0.94 [09cad98f-6e12-45fa-9f01-e7d90b9ea771]

  Then I did "show channels" to get the uuid:

  show channels
  uuid,direction,created,created_epoch,name,state,cid_name,cid_num,ip_addr,dest,application,application_data,dialplan,context,read_codec,read_rate,read_bit_rate,write_codec,write_rate,write_bit_rate,secure,hostname,presence_id,presence_data,callstate,callee_name,callee_num,callee_direction,call_uuid

  1 total.

  Then I did "uuid_recv_dtmf <uuid> 1234" like this:
  freeswitch at internal> uuid_recv_dtmf 09cad98f-6e12-45fa-9f01-e7d90b9ea771 1234
  -ERR no reply

  As you can see you do get "-ERR No Reply" but the operation itself works just fine.

    I tried the default conference dialplan with a real phone and works well.

      Do you actually try calling this with a real telephone to make sure that the extension is doing what you think it is doing?

        I'm trying the default conference in autoload_configs/conference.conf.xml,
        commented out the pin number line,

        but now when the ivr asks the pin number, for testing I tried
        to do this :

                <extension name="nb_conferences">
                        <condition field="${sip_to_uri}" expression="^(999)@$${domain}$">
                                <action application="answer"/>
                                <action application="info"/>
                                <!-- <action application="conference" data="confname at profilename+flags{mute|deaf|waste|moderator}+[conference pin number]"> -->
                                <action application="conference" data="$1-$${domain}@default"/>
                                <action application="send_dtmf" data="12345 at 120"/>
                        </condition>
                </extension>

        and this on CLI:

        expand uuid_send_dtmf ${uuid} 12345

        without success.
        How the default conference example accept DTMF ?

        Thanks

        F
