Asterisk PJSIP & LibreNMS

#1

Asterisk PJSIP monitoring is closed to new replies, but thought to share an updated script to /etc/snmp/asterisk for the search engines.

  • Returns number of total number of peers, number available, and unavailable
  • Works with existing “Asterisk - SIP Peers”, this just retrofits PJSIP data to LibreNMS Asterisk app SIP format
