Summary:                    app_channelredirect relies on ast_parseable_goto
which fails to redirect channels
Description: 
It seems like ChannelRedirect isn't working very well in trunk. I patched
ChannelRedirect to report the status in bug 0011553 for asterisk
1.4-trunk.
When I was porting this patch to trunk I stumbled on this issue.

The source av ast_parseable_goto that seems to fail even if there is a
vaild channel and destination. I have tested the following scenarious:
I place call http://bugs.digium.com/view.php?id=1 in either MusicOnHold(),
Meetme(), Playback() then I've a
call http://bugs.digium.com/view.php?id=2 that makes a
Channelredirect(call-numer-1-channelname,newcontext,newexten,1)
This always fails.

However if you do a core show channels after this unsucessful redirect you
will se:
Channel              Location             State   Application(Data)
Zap/pseudo-598993578 s at default:1          Rsrvd   (None)
SIP/callnumer1-08222 s at newcontext:0       Up      MeetMe(1,dm)

Note the newcontext:0...

And in the case you redirect channel http://bugs.digium.com/view.php?id=1 where
it does a Playback() the
redirect will occur after the Playback is finished. This will not happen
with the other applications thou.

Maybe I'm making a misstake, but this confuses me a lot...

I've tried this once again hoping I was mistaken.

I checked out revision SVN-trunk-r101344
and tried the following extensions.ael

context catchall {
        _X. => {
                Answer();
                Wait(1);
                Wait(888);
               }
}

After having one call waiting in Wait(888) I added the following row
before Wait(888):
                ChannelRedirect(SIP/0303350971-082294c8,test,s,1);

Then I called in on another phone.
The output was the following:
    -- Executing [0303350971 at catchall:1] Answer("SIP/0303350971-082294c8",
