[Freeswitch-users] one-way audio after playback+bridge

26 Jun 2009

      Hello!

I got a problem with one way audio, symptoms are:
firstly play audio file to channel A (A is hears sound)
secondly bridge channel B with A (A doesn't hear B).

Environment:
- no NAT
- User Agents being used X-Lite, EyeBeam, SJphone - same result for all of
them- no audio, Wireshark shows that there is no RTP-flow to A from
FreeSwitch
- dialplan:
<extension name="playback_media_file">
    <condition field="destination_number" expression="playmedia">
      <action application="answer"/>
      <action application="playback" data="test.wav"/>
    </condition>
  </extension>

<extension name="Local_Extension_from_SP">
      <condition field="destination_number" expression="^([0-9]{2,9})$">
        <action application="set" data="dialed_extension=$1"/>
        <action application="export" data="dialed_extension=$1"/>
      </condition>
      <condition field="${sip_to_host}" expression="^([^.]*)\..*$">

      </condition>
      <condition field="destination_number"

        <anti-action application="bridge" data="user/${dialed_extension}@

        <anti-action application="export"
data="sip_h_X-SPFrom="e;${sip_from_user}"e;<${sip_from_uri}>"/>
        <anti-action application="export"
data="sip_h_X-SPTo=<${sip_to_uri}>"/>
        <anti-action application="export"
data="sip_h_X-SPCallId=${sip_call_id}"/>
        <anti-action application="bridge"
data="sofia/external/${orgname}send2voicemail@
$${starpound_sip_app_server}"/>
      </condition>
    </extension>
- Call routing scheme:
user calls to FS, FS calls to my B2BUA which manage call with SIP 3pcc
Exact description what's going on is:
user A -> FS -(bridge)-> my B2BUA
Then my B2BUA transfers (using re-INVITE's), on behalf of user, call to
extension "playback_media_file" . After a while B2BUA transfer (re-Inviting)
user to extension "Local_Extension_from_SP". This should create a new call
to user B. As a result - A doesn't hear B, but B- is OK.
On the contrary, if a call is routed (by B2BUA) to the
"Local_Extension_from_SP" extension (ommiting "playback_media_file" ext) -
everything is OK.

What I've tried:
- set parameter "inbound-proxy-media" to "true" in Sofia profile
- set parameter "disable_rtp_auto_adjust to "true" in Sofia profile
Nothing helps.

Any help or thoughts would be MUCH appreciated!
