Hi François,
yes. Inaki already explained it nicely here:

Well, of course it does. Kamailio supports any method, including any
methods you yourself invent.
PRACKs are routed like any other non-INVITE request within a dialog. In
other words, they should be covered by loose_route().

New subject: Puzzling - INVITEs not making it to the fones
I'm seeing some *very* puzzling behavior from a bunch of our clients. Basically, the
INVITE never makes it to the fone, it looks like the upstream router/modem just swallows
it. The weird thing is, tweaking the username slightly resolves the issue, for a while at
least. And then, it stops again. Anyone seen anything like this before? Any ideas? Am
I missing something ridiculously obvious?
Fwiw, I've seen this behavior in setups with *no* SIP ALG, and *no* firewall. That
said, it really *does* look like a firewalling issue, doesnt it?
Here is a typical INVITE that is sent out from Kamailio. The username is mahesh.test204.
The "fix" is to simply change the name to "mahesh.test205", or
"mahesh.test20", or "ahesh.test204", etc.
Is there something obviously wrong with the INVITE perhaps? Bad format?

if the request is sent by kamailio but not reaching the phone, then is
something in the middle inspecting SIP and discarding (big brother?). Is
it a particular type of phone, or any phone? At first sight, the request
seems just fine. I cannot think of something else than alg/firewall in
the middle, unless the phone itself discards it.
Cheers,
Daniel
