Yes, I tried this also...
3 applications are needed here:

(command sent to FS1)
[app1] [CallA channel] [app2]:{sip_h_X-target_channel_id=[CallB
 channel]}sofia/bridging/123456 at ip:port,park inline

(dialplan in FS2)
<condition field="destination_number" expression="^(123456)$">
    &lt;action application=&quot;&lt;b&gt;app3"
data="${sip_h_X-target_channel_id}" />
 </condition>

app1 is uuid_transfer
app3 is eavesdrop
app2...? I cannot find anything that fits in here.
