Hello all, Just one last attempt at clearing the following points, if someone feels confident enough to answer:
* Does $nh(d) work when the Route header enforces the next-hop in an in-dialog request? * Is it safe to determine next hop for responses by looking at the first Via header only, or are there exceptions to this? Thanks!
