Hello,

based on the prompt in the snippets, kamailio is executed as a common user. Probably that user has no sufficient rights to write in the /var/run folder to create fifo/socket files. Either run kamailio as a root or grant appropriate privileges to the user starting kamailio.

Cheers, Daniel

Hi Daniel, Thank you for your answer.

How to run Kamailio with root or grant appropriate privileges. What is the Privilege or permission that Kamailio needed to run? Can you teach me?
