You mean, i need set auth_*_avp with credentials. set failure route, send request to auth_proxy (btw, how? ) and call uac_auth() in failure route, correct?

I've tried to use uacreg sql table and uac_reg_request_to, but there was some problems: 1) in uac_reg_request_to with mode 1 mistake (it found credentials only if l_uuid==l_username) i've opened ticket on bugtracker http://sourceforge.net/tracker/?func=detail&aid=3540479&group_id=13… 2) uac_reg_request_to changes uri in request and instead INVITE sip:B@othersip.com makes INVITE sip:AA@hisserver.com if comment out snprintf(ruri, MAX_URI_SIZE, "sip:%.*s@%.*s", reg->r_username.len, reg->r_username.s, reg->r_domain.len, reg->r_domain.s); and so on seems working, but I'm don't sure that such modification don't break something else (pretty sure that breaks, but don't know where exactly :) 3)uacreg table loaded on startup, and AFAIK there is no way to modify it dynamically, so if you change something in this table you MUST restart kamailio (not convinient) I've tried to make RPC for adding new record in htable (using reg_ht_add()), but it returns error and in log I can see ERROR: uac [uac_reg.c:313]: no more shm
