I'm using opensips and I did the configuration exactly like the tutorial but when I run the command that start opensips there is an error My PID file doesn't exist how to create it? normally the PID file is created automatically
root@ubuntu:/var/run/opensips# sudo opensipsctl start
INFO: Starting OpenSIPS :
ERROR:
PID file /var/run/opensips/opensips.pid does not exist -- OpenSIPS start failed
