Hi,
In my scenario kamailio is not a registrar, it's just a proxy
forwarding requests from asterisk to the provider.
I see.
As Juha said, REGISTER does not create a real dialog, since the
contact
in 200OK is the address of publisher not of destination. So a proxy
does
not have within-dialog like routing information.
So here is a hack you can try:
- add record route on your proxy
Record-Route in a REGISTER?? :)
- the provider should add its own record route to REGISTER reply --
if
it is kamailio, that is simple via append_to_reply() from textops,
just
before save() call.
This "hack" would work just in both, proxy and registrar, are
Kamailio. But,
if they are Kamailio then using PATH mechanism is the ellegant and
official
solution :)
As far as I understood, the original mail talks about Kamailio as
proxy and
Asterisk as registrar behind the proxy. Asterisk is not ready for that
scenario.
Well, if Asterisk has proper support for outbound proxys compiled, it
will work,
but only with *one* proxy in front of Asterisk.
Remember that Asterisk is designed to speak with dumb phones, to
send calls to
PSTN trunks and to play animal sounds by pressing DTMF's. But you
can always
code a PHP AGI to kill a database.
AGI doesn't work for databases though.
