[OpenSIPS-Users] outbound routing

[Jeff Pyle]

Julian,

The uac_registrant process to handle the registration to the remote proxy
and handling the 407 response on INVITE are unrelated operations.  You need
to catch the 407 in a failure_route and use the uac_auth()
<http://www.opensips.org/html/docs/modules/2.1.x/uac.html#id293810>
function to build the authentication header the 407 is looking for.  I've
found it to be finicky, particularly with respect to realm.  Look at the
uac_auth <http://www.opensips.org/html/docs/modules/2.1.x/uac_auth.html>
module to set the credentials.

Alternatively, you could use the b2b modules to answer the 407.  If you're
already using B2BUA-based topology hiding, this could make sense for you.
The b2b_entities documentation page says, "The module is able to respond to
authentication challenges if the uac_auth module is loaded first. The list
of credentials for b2b authentication is also provided by the uac_auth
module."  If you're doing lots of proxy-esque operations already, such as
dialog-based operations or accounting, then this most likely does not make
sense for you.  Stick with the first option.
