[sr-dev] t_check_trans with in-dialog requests

[Daniel-Constantin Mierla]

Hello,

iirc, ACKs for negative replies should be hop-by-hop, without any route 
set. Maybe you can paste a ngrep with invite/407/ack to see exactly what 
is there.

On the other hand, t_check_trans() for ack returns true if there is an 
active invite transaction associated with it, because ack itself does 
not create transaction, being a request that doesn't take a reply.

Cheers,
Daniel
