[OpenSIPS-Users] B2B Ack issue

Sorry if I have confused the list with all my paste links :)
Anca, if the ACK from 196.x.x.208 is not being matched to a transaction
correctly, then how does B2B module know to route the ACK to 41.x.x.33,
and it is even using the correct call id and from and to tags?

The first two bugs are no longer valid. You probably looked at an old
trace that the user pasted, I then asked him to update the code and
there are no longer this problems.
With the third, you are right, this is the point of the B2BUA to put
itself in the middle of the call and hide the topology.
