Hi Alex,
I had the same problem as you and I couldn't find a way to selectively
reply to via.
What I ended up doing is the following dirty trick...
Before a transaction is created for the processed message I do:
if (SOME CONDITION) {
remove_hf_value("Via[-1].rport");
msg_apply_changes();
}
For sure it would be better to be able to selectively set the reply_to_via
behavior.
Hope this helps.
Cheers,
Federico

force_rport seems to override any rport available in via, so reply_to_via
has no additional effects.
Thanks, that was helpful. But so, if force_rport() is not used, do I need
reply_to_via=1 in order to have replies go back to the declared port in the
Via rather than the received source port (as would be mandated by the
presence of client-injected rport)?
As for trusting client headers, I strongly agree. Unfortunately, sometimes
business requirements collide with our philosophies.
