Hi Guys

i run opensips and opensips-cp well on ubuntu 14.04 but i get error 

Array ( [0] => sorry -- cannot open write fifo

when i run opensips and opensips-cp on CentosOS 6 x86_64

that is so wired 

i pretty so i modify /etc/default/opensip  to make sure that opensips is run root use 

and i check the following lines in /usr/local/opensips_proxy/etc/opensips/opensips_residential_xxxxx.cfg

#### FIFO Management Interface
loadmodule "mi_fifo.so"
modparam("mi_fifo", "fifo_name", "/tmp/opensips_fifo")
modparam("mi_fifo", "fifo_mode", 0666)

i also check opensips_fifo in /tmp as the screenshot next

seems rights of fifo are correct

anyone faced my problem before?


there is another problem 

i read opensips support document http://www.opensips.org/html/docs/modules/1.11.x/carrierroute.html#id295092 for twice 

but i still dont figure out where and how can i generate a config file that required by carrierroute.so before opensips initialated . 


thanks for your help  very much
