Summary:                    [patch] Channelredirect hangs until hangup
Description: 
Channelredirect is not executing the context on the redirected channel when
callee activates a feature via features.conf --

The caller only continues through to the Meetme only after the CALLEE
hangsup . The callee is activating the feature by dialing the *6 once legs
are talking. 

features.conf --

conference => *6,self/callee,Macro,nway-start 

extension.conf ----

exten => _X.,1,Set(_DYNAMIC_FEATURES=conference) 
exten => _X.,n,Dial(ZAP/r1/2064792279)

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

[dynamic-invite] 
exten => 0,1,Read(DEST,dial,,i) 
exten => 0,n,Set(DYNAMIC_FEATURES=nway-inv#nway-noinv) 
exten => 0,n,Dial(ZAP/r1/${DEST}@dynamic-nway-dest,,g) 
exten => 0,n,Set(DYNAMIC_FEATURES=) 
exten => 0,n,Goto(dynamic-nway,${CONFNO},1) 
exten => i,1,Goto(dynamic-nway,${CONFNO},1) 


[dynamic-nway-dest] 
exten => _XXX,1,Dial(ZAP/r1/${EXTEN}) 

[macro-nway-start] 
exten => s,1,Set(CONFNO=300)
exten => s,n,ChannelRedirect(${BRIDGEPEER},dynamic-nway,${CONFNO},1) 
exten => s,n,Read(DEST,dial,,i) 
exten => s,n,Set(DYNAMIC_FEATURES=nway-inv#nway-noinv) 
exten => s,n,Dial(ZAP/r1/${DEST},,g) 
exten => s,n,Set(DYNAMIC_FEATURES=) 
exten => s,n,Goto(dynamic-nway,${CONFNO},1) 

The caller only continues through to the Meetme only after the CALLEE
hangus up.

Here is the reason why:

Aleg is executing dialplan logic already
Bleg is not

When Aleg activates the feature and does the ChannelRedirect on Bleg a new
PBX instance is created and starts executing. A "zombie" channel then takes
the place of Bleg in relation to Aleg.

When Bleg activates the feature and does the ChannelRedirect it simply
modifies the extension/context/priority on Aleg as it is already running a
PBX instance. Since a new one was not created it can not move on to the new
extension/context/priority until what is executing now (Dial) is finished.
