According to the wiki (and page 251 of the FS book, which has this exact same example) you need something like this:<div><br></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><pre><action application="bridge" data="{enable_heartbeat_events=5,nibble_rate=1,nibble_account=0838833133}sofia/external/$<a href="mailto:1@tel.co.th">1@tel.co.th</a>"/></pre>
</div><div>The link is <a href="http://wiki.freeswitch.org/wiki/Mod_nibblebill#Bill_base_on_B_leg_Only">http://wiki.freeswitch.org/wiki/Mod_nibblebill#Bill_base_on_B_leg_Only</a></div><div><br></div><div>In your example I don't know that you necessarily have a b-leg. How are you getting the call to the conference? Do you use originate? Or is it an inbound call?</div>
