Hi List
With the dispatcher module, you can use different ways of load balanced
and weighted serial or parallel forking.
Is there a corresponding way to achieve load balanced serial forking to
a destination set loaded from registered locations?
Use case:
Customer with a high availability set-up has two redundant PBX
registered to the same AoR.
Calls can not be sent in parallel as this would generate two concurrent
calls to the end device but call should be distributed evenly between
the two contacts registered with that AoR.
Yes, there is such a use-case, but it does not require `dispatcher`. You may use the
mode=1 argument to t_load_contacts() instead, provided the devices are registered with
equal q= values.
https://kamailio.org/docs/modules/5.8.x/modules/tm.html#idm1307
i.e.
route[REGISTRAR_SERIAL_TRY] {
if(!lookup("location")) {
send_reply("404", "Not Found");
exit;
}
t_load_contacts(1);
t_next_contacts();
# ...
# t_on_failure("REGISTRAR_SERIAL_TRY_NEXT"), t_relay(), etc...
}
failure_route[REGISTRAR_SERIAL_TRY_NEXT] {
if(t_is_canceled())
exit;
if(!t_next_contacts()) {
send_reply("408", "Request Timeout");
exit;
}
t_on_failure("REGISTRAR_SERIAL_TRY_NEXT");
t_relay();
}
