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.
