[Asterisk-Users] Why *3* entries?

[Matt]

When I do a coneference call and then join the two callers (and I hang
up) something odd happens.   I end up with 3 entries.. all with the
LAST number dialed... now I wouldn't really care if only 2 showed up
but the number dialed was the last one (at least the correct billing
was taking place)... however.... it appears 3 times...

and then conferenced them togethor...

When I hang up I receive all 3 in my record... based on the times..
it's like there is one generated when I call the first number.. then
one when I call the second (as well their should be)... then it seems
like the clid gets confused... (which again would be ok).. but why
when I hangup do I get a third call data record which seems to have 0
duration but a billable length of 314?

If I do a conference call... JUST a conference call.. the CDR show up correctly:

Any thoughts on why when doing a join on the two calls the CDR gets
all screwed up?
