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

The SIP trace you provided is not a proper Asterisk SIP debug trace.

To me it looks like the tail end of the initial call setup (the INVITE and
any 1xx responses, are missing from the beginning), followed by overlapped
re-invites from both ends.  The only thing that is slightly strange is that
one of the re-invites is not rejected because of the collision.

The fact that it proceeds from INVITE to OK in 31ms in one direction and
24ms the other way, and that there are no 18x responses, tends to support
the theory that these are normal, in dialogue, re-invites, not separate
dialogues.

To prove otherwise, you would need all the SIP headers, so that one can
see from and to tags, etc.
