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

To klaus3000:
i have isolated cdrs from my provider and from my server 
108 answered calls on provider cdrs
108 answered calls on my server cdrs
on my server cdrs calls show short calls of 1-5 seconds
on provider's switch it shows 10+ minutes,15+ minutes,20+mins,25+mins...

i cant reproduce it because,customer is not sending any more traffic and
also i cant afford loosing more money from that
