Summary:                    calls show some seconds on my cdrs - calls show
minutes on my carrier's cdrs!!
Description: 
I have huge problem,i use asterisk with a2billing
but is not problem with billing since asteriskcdrdb also has same thing on
cdrs.

I had somebody subscribing on my website and sending calls to different
countries special services. from cdrs i see short calls on my system 1-5
seconds.
the provider online cdrs report 10 minutes,20 minutes or more.
My provider says that this happened again to some of their customers they
say "your customer found a way to trick asterisk"
they say once the call is sent they cancel and after they send another
call with same call-id and. on sip debug from his site he sees that after
10 minutes my server sends OK for re-invite...
Im loosing money and i dont know if is a bug,my provider or anything else
i need your help,and if possible a security fix
directrtsetup=yes
canreinvite=yes
those are globally enabled
thanks

Can you provide more details about the CDRs, e.g. do your CDR and the CDR
of the provider start at the same time? Is there another call at the (near)
same happening (e.g. from the same user)?

Maybe the problem happens due to call transfers, e.g: User calls number1,
User calls2 number2, User transfers number2 to number 1. In such scenarios
it may happen that Asterisk writes CDRs at the time of the transfer (at
least that was the case with Asterisk 1.2)
