[OpenSIPS-Users] how to generate a config file for module carrierroute and getting error "sorry -- cannot open write fifo" on opensips-cp

[Liviu Chircu]

Hello Michael,

Have you restarted OpenSIPS after making the permission changes? I'm 
saying this because:

- you have correctly fixed the permissions issue in your script with:
modparam("mi_fifo", "fifo_mode", 0666)

- however, these changes are not yet visible in your /tmp directory!*
     prw-------  1 root root    0 10? 27 02:30 opensips_fifo*

It could also be possible that OpenSIPS is running on a different script 
than you are expecting.

Best regards,
