Hi admins,
I'm kinda new in this group and I'm not quite sure if I'm posting in a correct
way, advise if I'm wrong.
below is my post.
------------------------------------------------------------------------------------------------------------------------------------
I would like to activate Dispatcher module for apply Load Balance functionality
purpose.
but it's been hard to complete so far, I wonder if you can give me some advise
in below situation.
we have 2 Kamailios, the version is 4.3.3 ; we use domain for the SIP
registration.
we want to make Kamailios work in double active mode for SIP load balancing,
we have a F5 to do the domain name round robin to make two UAC regitering under
two UAS.
I have put the "route(DISPATCH) b4 PSTN in request_route.
when I try to make UAC-A call to UAC-B, it appears 407 proxy authentication
required.
we wiresharked, UAS has sent INVITE to UAS-B, but UAS-B sent the error code 407
to UAS-A
Is the configuration has to be set to "UAS-B accepting INVITE of UAS-A" ?
or the UAS-A should carrying the auth info into UAS-B ?
detail configuration as below.
------------------------------------------------------------------------------------------------------------------------------------

DISPATCHER Routing
route[DISPATCH] {
# round robin dispatching on gateways group '1'
if(!ds_select_dst("1", "4")) {
send_reply("404", "No destination");
exit;
}
xdbg("--- SCRIPT: going to <$ru> via <$du>\n");
t_on_failure("RTF_DISPATCH");
route(RELAY);
exit;
}
# Re-route in case of failure
failure_route[RTF_DISPATCH] {
if (t_is_canceled()) {
exit;
}
# next node - only for 500 or local timeout
if (t_check_status("500") || (t_branch_timeout() &&
!t_branch_replied())) {
if(ds_next_dst()) {
t_on_failure("RTF_DISPATCH");
route(RELAY);
exit;
}
}
}
