Hello. I have construction Asterisk --> Kamailio --> Providers
My provisers registered with UAC modure and stored at UACREG table.
Problem scenario is:
I ring from asterisk to provider
Asterisk --> Kamailio --> Providers
Call from asterisk come to kamailio with furi(Asterisk_clinet_local_number@asterisk) turi(external_number@kamailio)
Then, to forward INVITE to provider that Needed I use some manipulations to choose provider (it does not matter, it is only sql_queryes to some tables), and then modify invite with this code:
#$var(prov) - my.provider.ip #$var(trunk) - name_of_trunk
uac_replace_from("sip:$var(trunk)@$var(prov)");
$rd=$var(prov); $rp="5060"; $td=$var(prov);
remove_hf("Contact"); append_hf("Contact:<$var(trunk)@my.kamailio.domain:5068>\n","Contact"); #Then I get from database varibles to set it at failure route whet it needs to auth
#modparam("uac","auth_realm_avp","$avp(s:realm)") #modparam("uac","auth_username_avp","avp(s:uname)") #modparam("uac","auth_password_avp","$avp(s:passwd))")
sql_pvquery("ca","select auth_username, auth_password, realm from uacreg where auth_username='$var(trunk)'","$avp(uname), $avp(passwd), $avp(realm)");
So -after this manipulation I have write packet, that goes to my provider.
Then Provier sends me 407 answer and packet goes to failure_route
if (t_check_status("401|407")){ xlog("L_INFO", "Reply from provider on failure: $rs");
pv_printf("$avp(s:uname)","$var(uname)"); pv_printf("$avp(s:passwd)","$var(passwd)"); pv_printf("$avp(s:realm)","$var(realm)"); avp_print(); uac_auth(); xlog("L_INFO", "UAC_AUTH(): $rs"); t_relay(); } After that Call fails. When I look at at syslog I see that avp parametrs succesfull sets: INFO: avpops [avpops_impl.c:1484]: ops_print_avp(): p=0x7f63acec0650, flags=0x0113 INFO: avpops [avpops_impl.c:1488]: ops_print_avp(): #011#011#011name=<realm> INFO: avpops [avpops_impl.c:1496]: ops_print_avp(): #011#011#011val_str=<0 / 1> INFO: avpops [avpops_impl.c:1484]: ops_print_avp(): p=0x7f63acebe1a8, flags=0x0113 INFO: avpops [avpops_impl.c:1488]: ops_print_avp(): #011#011#011name=<passwd> INFO: avpops [avpops_impl.c:1496]: ops_print_avp(): #011#011#011val_str=<0 / 1> INFO: avpops [avpops_impl.c:1484]: ops_print_avp(): p=0x7f63ace697a8, flags=0x0113 INFO: avpops [avpops_impl.c:1488]: ops_print_avp(): #011#011#011name=<uname> INFO: avpops [avpops_impl.c:1496]: ops_print_avp(): #011#011#011val_str=<0 / 1> INFO: avpops [avpops_impl.c:1484]: ops_print_avp(): p=0x7f63acec0240, flags=0x0113 INFO: avpops [avpops_impl.c:1488]: ops_print_avp(): #011#011#011name=<realm> INFO: avpops [avpops_impl.c:1496]: ops_print_avp(): #011#011#011val_str=<my.provider.com / 15> INFO: avpops [avpops_impl.c:1484]: ops_print_avp(): p=0x7f63acec0308, flags=0x0113 INFO: avpops [avpops_impl.c:1488]: ops_print_avp(): #011#011#011name=<passwd> INFO: avpops [avpops_impl.c:1496]: ops_print_avp(): #011#011#011val_str=<mYPa$$wd / 8> INFO: avpops [avpops_impl.c:1484]: ops_print_avp(): p=0x7f63acea3d40, flags=0x0113 INFO: avpops [avpops_impl.c:1488]: ops_print_avp(): #011#011#011name=<uname> INFO: avpops [avpops_impl.c:1496]: ops_print_avp(): #011#011#011val_str=<myTrunk/ 16> But Next I see:
ERROR <script> : AUTH_UAC(): <null>
As I see AUTH_UAC() don`t want to set Auth parameters.
My question is Why?
Thanks!
