[SR-Users] Registering "upstream" with the uac module, but with authentication

Hi, I'm making slow but steady progress with my Kamailio project. My next task: I need to "relay" a registration to an upstream service. IE when one or more devices registers against my local registration service, I need to initiate a corresponding registration upstream. If all my local devices unregister, all all the registrations lapse, I want to drop the upstream registration. There is an example a bit like this in the Asterisk integration example. However in that case the Asterisk doesn't challenge for authentication. My upstream does. I can't find anything in the uac module docs about authenticating. Is there any way to handle this. One thing I did try was to create "uacreg" as a view, and use that as the source of upstream registrations: CREATE VIEW `uacreg` AS select distinct `s`.`id` AS `id`,`l`.`username` AS `l_uuid`,`l`.`username` AS `l_username`,`s`.`domain` AS `l_domain`,`l`.`username` AS `r_username`,`s`.`domain` AS `r_domain`,`s`.`domain` AS `realm`,`l`.`username` AS `auth_username`,`s`.`password` AS `auth_password`,concat('sip:',`s`.`domain`,':5060') AS `auth_proxy`,timestampdiff(SECOND,now(),`l`.`expires`) AS `expires` from (`location` `l` join `subscriber` `s`) where (`l`.`username` = `s`.`username`) This kinda worked - but didn't quite track the registration status. Do you think this idea has promise? Maybe something similar that works using triggers rather than a straight view might work better?
