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
