Hi, somebody can help me?? I am trying to set up OpenSer 1.0.1 like dispatcher to loadbalance and failover but when I use ds_next_dst() for failover I obtain the next error: 0(19024) parse error (128,25-26): unknown command, missing loadmodule?
ERROR: bad config file (1 errors)
My config file is the next:

Look line 128, columns 25 and 26... there is something wrong.... ;)
Edson.
P.S.: After fixing, try openser c <Your-config-file> to get rid all syntax errors. :-)

I believe that the failover in the dispatcher was only introduced in the OpenSER 1.1 (not 1.0.1).

Wouldn't you do the following (OpenSER will do 100 for you... and you don't need to forward() and t_relay()...
ds_select_dst("2", "0"); t_on_failure("1"); if( !t_relay()) { sl_reply_error(); return; };
Just a thought...
Also, in your example, failure_route[1] will be called for things like 404 (not found), and 486 (busy), and you will be attempting the same thing again using different media gateways etc...
I get around this by using a t_on_reply("1") and in onreply_route[1] do
if( status =~ "18[0-9]" ) { t_on_failure("0"); }
So if you get a provisional response from your media gateway (ie a 180 Ringing, or 183 Session Progress) you don't do any more gateway attempts if you then get a 4xx/5xx/6xx response....
You may also wish in route{} to split out the handling of CANCEL, BYE, and INVITE. You want your INVITE to do the ds_select_dst(), but you should just be able to t_relay() your CANCELs and BYEs and OpenSER will match them to the selected destination based on an existing transaction.
YMMV but this is similar to what I have been doing and testing with OpenSER.

Hi,
yes, that's right. OpenSER 1.0.1 dispatcher module does not contain the function/parameter you want to use. See: http://openser.org/docs/modules/1.0.x/dispatcher.html You need to use the 1.1.0 version: http://openser.org/docs/modules/1.1.x/dispatcher.html
