I become crazy to realize a serial forking.
I try to use load_contacts() and next_contscts().
This is my openser.cfg nd my location table:
In teory when I call 309 at 192.168.9.98 the location with the q value
equal to 0.80 it is the first but it is processed only the location
309 at 192.168.9.131.
Help!!!
