[Freeswitch-users] missing 3 seconds of audio on bridge calls

[Angel Carpintero]

Hi guys, 
 
 I've a strange issue with FS , version svn -r10584 ,
when FS bridges a call first 3 seconds of audio are missing , looks that
only happens on PSTN calls and using ringback or transfer_ringback. This
only happens in calls from PSTN , not from VOIP. Some scenarios i tried
to isolate this issue :


- Issue

PSTN --> FS ( brigde ) ringback/transfer_ringback -> PSTN

- Good setting bypass_media before run bridge but i need rtp in FS path

PSTN --> FS ( brigde ) ringback/transfer_ringback -> PSTN

- Good 

PSTN --> FS ( brigde ) WITHOUT ringback/transfer_ringback -> PSTN

- Always good

VOIP --> FS ( brigde ) -> PSTN


Dialplan has nothing wrong ( i guess ):

<extension name="Transfers">
    <condition field="destination_number" expression="^1??XXXXXXXXXX$">
      <action application="answer"/>
      <action application="speak" data="cepstral|Allison-8kHz|blah"/>
      <action application="set" data="hangup_after_bridge=false"/>
      <action application="set" data="playback_terminators=#"/>
      <action application="set" data="ringback=$${us-ring}"/>
      <action application="set" data="transfer_ringback=
$${hold_music}"/>
      <action application="set" data="effective_caller_id_name=
${caller_id_name}"/>
      <action application="set" data="effective_caller_id_number=
${caller_id_number}"/>
      <action application="set" data="originate_timeout=30"/>
      <action application="set" data="call_timeout=30"/>
      <action application="bridge"
data="sofia/default/18008226235 at PSTN_GW"/>
      <action application="speak" data="cepstral|Allison-8kHz|Transfer
finished"/>
      <action application="hangup"/>
    </condition>
  </extension>



Any ideas ?

Attached log of FS ( F8 from console ).
