Not sure about using ESL, but here's an example on how to do it with Lua:<div><br></div><div><a href="http://wiki.freeswitch.org/wiki/Bridging_two_calls_with_retry">http://wiki.freeswitch.org/wiki/Bridging_two_calls_with_retry</a><br>
<br></div><div>Simplifying the code on that example though, here are the basics:</div><div><br></div><div><div>session1 = freeswitch.Session(ostr1);</div><div>if (session1:ready()) then</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-- Set ringback</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>session1:setVariable("ringback", "%(2000,4000,440,480)");</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>session2 = freeswitch.Session(ostr2, session1);</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>if (session2:ready()) then</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>freeswitch.bridge(session1, session2);</div><div><br></div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>-- Hangup session2 if session1 is over</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>if (session2:ready()) then session2:hangup(); end</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>end</div><div><span class="Apple-tab-span" style="white-space:pre"> </span></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-- hangup when done</div>
<div> if (session1:ready()) then session1:hangup(); end</div><div>end</div></div><div><br><br></div><div>ostr1 and ostr2 should be your dialstrings, something like: {ignore_early_media=true,originate_timeout=90,hangup_after_bridge=true}sofia/gateway/yourgateway/phonenumber</div>

Try the transfer_ringback var. Check the wiki for details.<br>
