Hello!
Acc to 3261, 16.4:
the proxy MUST replace the Request-URI in the request with the last
value from the Route header field, and remove that value from the
Route header field. The proxy MUST then proceed as if it received
this modified request.
The loose_route() function does only the half on my
if (looose_route()) {
..
t_relay()
..
}
script. It replaces the RURI with the value of the last Route header,
but then doesn't remove it, causing problems on the last hop.
The strict.txt contains a ACK with comes in strict and leaves loose -
with the Route header.
Aliases are configured with ip.ip.ip.ip and ip.ip.ip.ip:5060.
Why is the Route header not stripped?
