More specifically FS core converts every member from their codec to L16 which is given to the conference. The conference combines all speaking channels and the resulting L16 is given back to the core to send to the members, the core converting to the correct codec for each member.

The conference itself doesn't do any codec stuff - FreeSWITCH core does. All I can say is compare the working versus non-working logs and look for clues.

nohgint strange on logs.
but I guess it's a codec and rate problem.
tried with different SIP phones and it works.
how a conference manage the codecs  ?
I know the rate can be set in profile,
but how conference codec is managed
 if all members have different codec and rate ?

What do you see in the debug logs? Did you compare the logs for a working vs. non-working call? Anything different?

when the first member creates and enters in a new conference
everything is ok. but if a new memeber enters there is no audio

I have a very simple conference dialplan like this
 
        <extension name="create_conference">
                <condition field="${sip_to_uri}" expression="^000(\d{10,15})@$${domain}$">
                        <action application="set" data="instant_ringback=true"/>
                        <action application="ring_ready"/>
                        <action application="sleep" data="3000"/>
                        <action application="answer"/>
                        <action application="conference" data="$1-${domain_name}@wideband"/>
                </condition>
        </extension>
 
I tried to add
<action application="export" data="absolute_codec_string=speex@16000k"/>
 
but no success
 
Thanks
