[Freeswitch-users] Call Waiting + FIFO

Tue Jul 29 00:36:08 MSD 2014

if you run the command "fifo debug 2" it will debug log the sql statements.  For reference, the find_consumers sql looks something like:

static void find_consumers(fifo_node_t *node)                                                                                                                     
{                                                                                                                                                                 
    char *sql;                                                                                                                                                    

    sql = switch_mprintf("select uuid, fifo_name, originate_string, simo_count, use_count, timeout, lag, "                                                        
                         "next_avail, expires, static, outbound_call_count, outbound_fail_count, hostname "                                                       
                         "from fifo_outbound "                                                                                                                    
                         "where taking_calls = 1 and (fifo_name = '%q') and ((use_count+ring_count) < simo_count) and (next_avail = 0 or next_avail <= %ld) "     
                         "order by next_avail, outbound_fail_count, outbound_call_count",                                                                         
                         node->name, (long) switch_epoch_time_now(NULL)                                                                                           
                         );                                                                                                                                       

Note that the outbound_call_count is part of the order by, if there are other available agents, its most likely going to hit them first, before someone already on the phone, which makes sense to me.

All i know is that if i set simo to 20 or 100, then issue fifo list <fifo name> i see that the correct value.
