Well these are two different dispatcher groups, one is SET:1 10.2.45.98
where the calls are routed - the other one is SET:2 which you are
definitely not calling in your ds_select() function.
Also the flags=IP are, I think, saying that asterisk servers are inactive
and kamailio is probing them, not sure about it. mine always show me
flags=AP for active servers.
Also how have you defined the
ds_ping_reply_codes
http://www.kamailio.net/docs/modules/3.2.x/modules_k/dispatcher.html#id2495999
Parameter such that if asterisk responds with a 484 or 404 or anyother
negative response to the dispatcher OPTIONS SIP ping then consider it
active.
Hope this will get your issue resolved.
The thing is the dispatcher in kamailio or load-balancer in OpenSIPS both
set the Initial flags of all the servers in the table to Active/Enabled !
that means if I have a server which is down and I reload the dispatcher
module it will mark that down server to UP and my calls will timeout trying
to send calls to that instance !
Thanks,
Sammy
