asterisk users - Jul 2009 - MeetMe time doesn't show up in CDRs?

Hello,

I'm working on some dialplan rules to pull multiple users into a
conference call.  I have some fairly straightforward rules which start
up a new MeetMe conference, allow escape with the * key to invite more
users, then use a features.conf sequence to bring the new user into
the conference with ChannelRedirect.

The problem I'm running into is the time in the MeetMe conference
doesn't seem to show up in the CDRs anywhere.

I tried creating the MeetMe conference, bringing one user in, bring
another in, then keeping the conference open for 4 more minutes.  I
ended up with 4 CDR entries.  None of the times is anywhere near 4
minutes; they don't even add up to 4 minutes.

Any idea how I can get that time to show up in a CDR entry, or any
details of how CDRs should work with MeetMe and ChannelRedirect?

Here are my 4 CDR entries:

My dialplan rules look like this; I come in to cob-meetme from an
extension earlier in the plan, with MY_ACCOUNTCODE and COB_CONFNO
already set.  The callout context places an outgoing call.

    [cob-meetme]
    exten => _XXX,1,Answer
    exten => _XXX,n,Set(CDR(accountcode)=${MY_ACCOUNTCODE})
    exten => _XXX,n,Set(MEETME_EXIT_CONTEXT=cob-meetme-escape)
    exten => _XXX,n,MeetMe(${EXTEN},d1qMX)
    exten => _XXX,n,Hangup
    
    [cob-meetme-escape]
    exten => *,1,Set(CDR(accountcode)=${MY_ACCOUNTCODE})
    exten => *,n,Read(DEST,,0,,1,0)
    exten => *,n,Set(DYNAMIC_FEATURES=cob-join#cob-nojoin)
    exten => *,n,Dial(Local/${DEST}@callout,,g)
    exten => *,n,Set(DYNAMIC_FEATURES=)
    exten => *,n,Goto(cob-meetme,${COB_CONFNO},1)
    
    [macro-cob-join]
    exten => s,1,Set(CDR(accountcode)=${MY_ACCOUNTCODE})
    exten => s,n,ChannelRedirect(${BRIDGEPEER},cob-meetme,${COB_CONFNO},2)
    
    [macro-cob-nojoin]
    exten => s,1,Set(CDR(accountcode)=${MY_ACCOUNTCODE})
    exten => s,n,SoftHangup(${BRIDGEPEER})

I have these in features.conf and enabled in the dialplan:

    cob-join   => *33,self/both,Macro,cob-join
    cob-nojoin => *34,self/both,Macro,cob-nojoin

Thanks!
