[Freeswitch-users] .wav/.mp3 recording problems - lag

[Bogdan Patrascoiu]

Hello,

My dial plan looks something like this :

<extension name="provider" >
   <condition field="destination_number" expression="^(.+),(.+),(.{10})$">
       <action application="set"
data="record_file=$${base_dir}/recordings/$1_$2_${strftime(%Y-%m-%d-%H-%M-%S)}_$3_${caller_id_number}.wav"/>
       <action application="set" data="tariff=0.02"/>
       <action application="set" data="id_proiect=$1"/>
       <action application="set" data="id_operator=$2"/>
       <action application="set" data="real_destination=$1,$2,$3"/>
       <action application="set" data="transfer_after_bridge=*3472"/>
       <action application="bind_meta_app" data="0 a s transfer::*3472"/>
       <action application="record_session" data="${record_file}"/>
       <action application="bridge"
data="sofia/gateway/53625621${caller_id_number}/$3"/>
   </condition>
</extension>

After a lot of digging i found this :
http://www.mail-archive.com/freeswitch-users@lists.freeswitch.org/msg10499.html

So the answer seems to be this :

       <action application="set" data="enable_file_write_buffering=false"/>

What do you think? I implemented this and so far i haven't got any new
complains, but as the happening was totally random i am not sure of
this solution's certainty.

Thanks,

Bogdan
