If using asterisk realtime, create a view of the sip users table with password set to
null. This will scale if sharing databases which are replicated.
Then you can use Kamailio to authenticate and Asterisk to handle media.

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..

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users 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.
