Hi Kalus,

the basic usage of this function is for dealing with CANCELs and local 
end2end ACKs - you may catch them and perform more checking.
For example, if you get an ACK with no routing info (no Route), ACK 
which doesn't belong to any INVITE transaction, I may drop it since 
something went (bad routing??) wrong and the ACK will spiral on your 
proxy....

regards,
Bogdan
