I've found that it occurs after any bridge, its not specific to the
originate command.
Would you require a wireshark trace or the output of the freeswitch console?
The scenario below reproduces the issue ...
Test extension
<extension name="Inbound_Routing">
<condition field="destination_number" expression="^2003$">
<action application="export" data="dialed_extension=$1"/>
<action application="export" data="transfer_ringback=$${uk-ring}"/>
<action application="set" data="RECORD_TITLE=Title goes here"/>
<action application="set"
data="rtp_manual_rtp_bugs=SEND_LINEAR_TIMESTAMPS"/>
<action application="export" data="send_silence_when_idle=false"/>
<action application="export" data="bridge_generate_comfort_noise=false"/>
<action application="export" data="rtp_enable_vad_in=false"/>
<action application="export" data="rtp_enable_vad_out=false"/>
<action application="export" data="fire_talk_events=true"/>
<action application="export" data="fire_not_talk_events=true"/>
<action application="export" data="recording_id=${uuid}"/>
<action application="set" data="media_bug_answer_req=true"/>
<action application="answer" />
<action application="playback"
data="tone_stream://L=100;%(400,200,400,450);%(400,2000,400,450)"/>
</condition>
</extension>
I originate a call from a polycom handset using g722 to the extension above.
I originate a call using the verto client to the extension above.
I get the uuids of the channels using show channels and use uuid_bridge
[uuid1] [uuid2] to merge the channels.
