i don't know about core functions (in fact i was not able to find them in core cook book, but i'm pretty sure they must be there somewhere), but if you use lcr, you call load_contacts() in your route block, then set a failure route, then call next_contacts() and t_relay. in your failure route, you then just keep on setting failure route again and call next_contacts()/t_relay again as long as next_contacts() returns 1, i.e., there are still contacts left. see lcr README.

Hi,

I am trying to implement Serial forking using the lcr module. Here is how my cfg file looks like:

modparam("lcr|usrloc|auth_db|avpops|domain", "db_url", "mysql://xxxxxx:xxxxxx@localhost/xxxxx") modparam("lcr","lcr_table","lcr") modparam("lcr", "contact_avp", "$avp(i:711)")

### Try for Serial Forking if (load_contacts()) { xlog("L_INFO","In load_contacts()\n"); xlog("L_INFO","load_contacts() - avp(i:711) = $avp(i:711) - ds = $ds\n"); } if (!next_contacts()) { sl_send_reply("500", "Server Internal Error"); exit; } else { xlog("L_INFO","next_contacts() - avp(i:711) = $avp(i:711) - ds = $ds\n"); t_on_failure("5"); t_relay(); #exit; };

failure_route[5] { xlog("L_INFO","Entered failure route for Serial Forking\n"); t_on_failure("5"); if (next_contacts()) { xlog("L_INFO","Failure Route, Next contacts\n"); append_branch(); t_relay(); } exit; }

### End Try for Serial Forking

I am unable to simulate serial forking using the above configuration. Here is what the logs say:

9(6228) load_contacts(): DEBUG: Nothing to do - no branches! 9(6228) In load_contacts()::VSPL 9(6228) load_contacts() - avp(i:711) = <null> - ds = <null> 9(6228) next_contacts(): DEBUG: No AVPs -- we are done! 9(6228) next_contacts() - avp(i:711) = <null> - ds = <null>

When I check the location (mysql) db, it displays the entries and the q parameters...

What I am doing wrong?

Thanks again Juha... Will try this out..
