Hi,

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

Here is the scenario: 
1. user "ua1" calls user "ca1" 
2. "ua1" then presses the feature code "*0" to redirect "ca1" to 
conference room 300 
3. "ua1" then dials the user "33" 
4. user "ua1" and "33" are connected 
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 at nway-conf-dest-7ecf,1<ZOMBIE>" 

Here is my dial plan: 

[manu] 
exten => ca1,1,Dial(SIP/ca1,,wWtTkKrR) 

[nway-conf] 
exten => _.,1,Answer 
exten => _.,n,Set(CONFNO=${EXTEN}) 
exten => _.,n,Set(MEETME_EXIT_CONTEXT=nway-conf-invite) 
exten => _.,n,Set(DYNAMIC_FEATURES=) 
exten => _.,n,MeetMe(${CONFNO},pdMX) 
exten => _.,n,Hangup 

[nway-conf-invite] 
exten => 0,1,Read(DEST,dial,,i) 
exten => 0,n,Set(DYNAMIC_FEATURES=nway-conf-inv#nway-conf-noinv) 
exten => 0,n,Dial(Local/${DEST}@nway-conf-dest,,g) 
exten => 0,n,Set(DYNAMIC_FEATURES=) 
exten => 0,n,Goto(nway-conf,${CONFNO},1) 
exten => i,1,Goto(nway-conf,${CONFNO},1) 

[nway-conf-dest] 
exten => _.,1,Dial(SIP/${EXTEN}) 

[macro-nway-conf-start] 
exten => s,1,Set(CONFNO=300) 
exten => s,n,ChannelRedirect(${BRIDGEPEER},nway-conf,${CONFNO},1) 
exten => s,n,Read(DEST,dial,,i) 
exten => s,n,Set(DYNAMIC_FEATURES=nway-conf-inv#nway-conf-noinv) 
exten => s,n,Dial(Local/${DEST}@nway-conf-dest,,g) 
exten => s,n,Set(DYNAMIC_FEATURES=) 
exten => s,n,Goto(nway-conf,${CONFNO},1) 

[macro-nway-conf-ok] 
exten => s,1,ChannelRedirect(${BRIDGEPEER},nway-conf,${CONFNO},1) 

The application map defined in features.conf is: 
[applicationmap] 
nway-conf-start => *0,self/caller,Macro,nway-conf-start 
nway-conf-inv => **,self/caller,Macro,nway-conf-ok 
nway-conf-noinv => *9,self/caller,Macro,nway-conf-notok 

The output logs on Asterisk console:
