[OpenSIPS-Users] help with drouting

[Bogdan-Andrei Iancu]

Hi Justin,

The DR module exports only 2 functions - do_routing() which selects a 
list of GWs to be used for the call ad use_next_gw() used for 
consuming/using the next GW from the list. See:
       
http://www.opensips.org/html/docs/modules/devel/drouting.html#id272402

So, in your script, when you want to send the call to PSTN (depending on 
the logic you have there), you use do_routing() to get the list of GWs 
and use the first one. Before sending the call out, arm a failure route 
where (in case of GW failure - like 5xx reply) you can use the 
use_next_gw() to do serial forking.

Regards,
Bogdan

I've already set up Opensips-CP and have made the necessary database modifications, as well as added the proper loadmodule and modparam blocks for drouting.so, but I'm not sure how to proceed in the opensips.cfg, and I haven't been able to find any tutorials that cover this. If someone could point me in the right direction of a good tutorial, or make recommendations about my opensips.cfg file (routing portion included below) I would appreciate it.
