Thanks Daniel.
Will take a look to that.

If Asterisk is still do it the authentication, then
likely it is not much
gain on overall scalability. Maybe you can just use kamailio as an edge
proxy with Path enabled.
Otherwise, the requests generated with uac_req_send() don't get in
failure_route. You have to set the auth user/password in the $uac_req(...)
fields -- see the variables core cookbook for them. On the other hand, this
is not enough, you have to deal also with authentication for other
requests, such as INVITEs/SUBSCRIBEs/etc.
Cheers,
Daniel

I have it working, authenticating in Kamailio. And just works.
But there is a farm with lots of Asterisk and i was looking for an easy
way to do not modify secret= and permit= on every Asterisk Machine... Thats
why i was looking for that..

Why not just authenticate on Kamailio in that
case?
Also, be aware that the Authorization Username ($au) is included in SIP
digest authentication. $au and $fu aren't necessarily the same, but on
most end points the default is to use the same value for both. If you
manipulate $fu or $au it may cause auth issues.

Hi Marrold. I want to authenticate user on
Kamailio but want Asterisk to
see them registered with kamailio ip as contact.
I making also some manipulations in $fu as users are different
(emp_xxx_ext) in kamailio than in Asterisk xxx_ext
Thanks

Why not just relay the registration messages to
Asterisk itself? What's
the use case?
Cheers
