Hello,

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? Can anybody help me with configuration kamailio
to authenticate call on
3rd party server?
I want to authenticate(and proxy) call's on other server.
for example, user A have account on my server(let it be A(a)myserver.com)
and account on other server (let it be AA(a)hisserver.com)
myserver.com keeps A's credentials for AA(a)hisserver.com
when A is registered on myserver.com, he make call to B(a)othersip.com
(using myserver.com as a proxy)
Kamailio on myserver authenticate itself on hisserver as
AA(a)hisserver.com,
makes call to destination, and connect it to A.
How can I setup kamailio for such behavior?
Which module should I use?
UAC seems can authenticate on another server, but I don't sure that it
do
what I want. (I've tried it, but without much success)
indeed, the uac module
is the one that can provide what you want, with
some limitations in regard to cseq incrementation. You have to set a
failure route and if the reply code is 407, the sent the realm/username
and password to the avps specified by the appropriate module parameters
-- the next tree at:
*
http://kamailio.org/docs/modules/stable/modules_k/uac.html#auth-realm-avp-id
Then call uac_auth() and relay again.
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
If you have a lot of records, you need to
allocate more shared memory,
via -m command line parameter.
uacreg is to register for incoming calls, it is not used for
authentication of outgoing calls. Use uac_auth() instead, as I said in
previous email.
Cheers,
Daniel
