<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">I am trying to achieve 3-way conferencing
taking hint from wiki link http://www.voip-info.org/wiki/view/Asterisk+n-way+call+HOWTO</font>
<br>
<br><font size=2 face="sans-serif">Here is the scenario: </font>
<br><font size=2 face="sans-serif">1. user "ua1" calls user "ca1"
</font>
<br><font size=2 face="sans-serif">2. "ua1" then presses the
feature code "*0" to redirect "ca1" to conference room
300 </font>
<br><font size=2 face="sans-serif">3. "ua1" then dials the user
"33" </font>
<br><font size=2 face="sans-serif">4. user "ua1" and "33"
are connected </font>
<br><font size=2 face="sans-serif">5. Now when "ua1" presses
the feature code "**" to redirect user "33" to same
conference room 300, there is error thrown on Asterisk console that "res_features.c:1415
ast_bridge_call: Bridge failed on channels SIP/ua1-ac750040 and AsyncGoto/Local/33@nway-conf-dest-7ecf,1<ZOMBIE>"
