You could also send the 100 trying response at the beginning of the
script. the the processing delay is almost 0 :-)

It seems to me that the a proxy processing an
initial request directed to it
should be able to insert such a header in a reply, but that Kamailio does
not have support for timing functions that perform these measurements
automatically. Would you agree?
Well, a workaround could be take the current time at the top of the
script, then just before the t_relay (the real time it takes to the
proxy to process the request) calculate the delta time and generate a
stateless 100 reply adding suche header. Then call to t_relay with the
proper flag to avoid sending a new 100 response.
