[SR-Users] received parameter in route URI not used despite path use_received set to 1

[Easy Rider]

Hi

I've run the test again with log level set to 4, and I don't see anything
related to route header parsing, I don't see any trace of the received uri
value
I've also tried with outbound module loaded, no change
I've also tried with WITH_NAT defined or not, no change

Cheers
