Does sipp respect the Route, Record-Route, Via, or Contact headers for sending message?

Hi,

I want to run an UAC scenario which maps received Record-Route Headers in 200_OK into Route Headers in the ACK message.
Using the fields [routes] and [next_url] for building the ACK, it looks OK. However, the UDP packet containing the ACK is not send to the
address in the Route Header (as it should be), but still to the address of the Request-URI of the ACK.

If I want to use route header to send packet, what should I do? now I am using Sipp v3.7.1.

SIPp will (unfortunately in my mind) stick to the CLI configured next-hop address, until you override it.
