My two cents:

my pertinent config part is:

loadmodule "dispatcher.so"

modparam("dispatcher", "list_file", "/etc/openser/dispatcher.list") route{ ...

if (method=="INVITE"||method=="CANCEL") { # INTERNATIONAL/NATIONAL CALLS DIALED WITH 0+ if (uri=~"^sip:0"){ xlog("L_ERR", "\n************** INTERNATIONAL/NATIONAL CALL DIALED WITH 0+ ************\n"); route(5); } } ... }

route[5] {

# AUTHORIZE AND ROUTE CALL

if(!proxy_authorize("","subscriber")) { proxy_challenge("","0"); exit; }

xlog("L_NOTICE", "\n************** GOT OUTSIDE CALL ************\n"); ds_select_dst("1","2"); sl_send_reply("100","Trying"); forward(); exit(); }

and my dispatcher.list is:

# group sip addresses of my asterisk for rtps 1 sip:IP_SERVER_1:5060 1 sip:IP_SERVER_2:5060

Works like a charm! beautiful!

Have fun!

User dispatcher module, openser does not do load balancing based on SRV records itself.

Hi, I've got a problem with openser servers and load balancing. Current setup contains 2 asterisks and 2 opensers. I've got a srv record xxx for both asterisk-1 and asterisk-2 - same priorities and weights. Openser's config runs basically:

rewritehostport("xxx"); t_relay();

But all packets go to first host on the list anyways. For example now I get this from dns (same order):

_sip._udp.xxx. 300 IN SRV 1 50 5060 asterisk-2 _sip._udp.xxx. 300 IN SRV 1 50 5060 asterisk-1

and got 6 calls on asterisk-2 and none on asterisk-1. If I change the order, all calls go to the first host on the list. Shouldn't openser do load-balancing in this scenario? I don't use any options in t_relay().

Thanks for ideas.
