Dear All,
I am trying to use Kamailio 3.1.x server (called LB here) as the Load
Balancer for two other Kamailio server (called server01 and server02 here) .
Client A -----> Kamailio LB -----> Kamailio server01
Client B -----> Kamailio LB -----> Kamailio server01
If I dont use LB here , and letting Client A and B connect to Kamailio
server01 directly , all the communication is fine.
While using Kamailio LB ,without luck, although the sip client A and B
get 200 from server01 for Register,
they cannot reach each other for "Message" and "Invite".
It will be great appreciated if anyone can give a hint.
my config for Kamailio LB is as below :
==========================================
....
debug=2 # debug level (cmd line: -dddddddddd)
fork=yes
log_stderror=yes # (cmd line: -E)
children=2
check_via=no # (cmd. line: -v)
dns=off # (cmd. line: -r)
rev_dns=off # (cmd. line: -R)
port=5060
# for more info: sip_router -h

exit;
};
# if (!method=="REGISTER")
# record_route();

forward();
exit;
}
