Managing File Descriptors
Asterisk can consume a large number of file descriptors, especially as your system scales. Increase the limit to handle more simultaneous calls:
- PAM-Based Linux: Edit
/etc/security/limits.confand add the following lines (adjust numbers as needed):root soft nofile 4096 root hard nofile 8196 asterisk soft nofile 4096 asterisk hard nofile 8196 - Generic Unix: Add
ulimit -n 8192to the script that starts Asterisk.
Time Synchronization: Maintaining Accurate System Time
Asterisk, especially with SIP phones, is sensitive to time discrepancies. Use a time synchronization package to keep your system clock accurate:
ntpd/ntpsecchronydsystemd-timesyncd
Install and configure one of these packages to prevent SIP registration failures and internal process errors.
Configuration Files: The Heart of Your Asterisk System
