Well why would the header to damaged or missing. I have updated the 
config to the following and it still doesnt work. If I look at the 
header info with windows by going to file properties it doesnt list 
anything in the header info. The file is just a bunch of high pitched 
noise if I dont import as raw. I can hear the audio fine when importing 
raw and 8000hz rate. I am not sure what else I need to do to make this 

I followed the steps listed on: 

<extension name="bandwidth.10d" >
    <condition field="destination_number" expression="^(\d{10})$" >
        <action application="set" 
data="sip_h_X-accountcode=${accountcode}" />
        <action application="set" data="sip_h_X-Tag=" />
        <action application="set" data="call_direction=outbound" />
        <action application="set" data="hangup_after_bridge=true" />
        <action application="set" 
data="effective_caller_id_name=${outbound_caller_id_name}" />
        <action application="set" 
data="effective_caller_id_number=${outbound_caller_id_number}" />
        <action application="set" data="inherit_codec=true" />
        <action application="set" data="record_sample_rate=8000" />
        <action application="set" data="RECORD_TITLE=Recording

        <action application="set" data="RECORD_SOFTWARE=FreeSWITCH" />

        <action application="set" data="RECORD_DATE=${strftime(%m-%d-%Y

        <action application="set" data="RECORD_ARTIST=FreeSWITCH" />
        <action application="set" data="RECORD_COPYRIGHT=(c) 2013" />

        <action application="record_session"
