Zabbix pjsua notification

When testing a new notification method using pjsua , I get a message:

Alertscript connection timeout of 3 seconds exceeded when connecting to Zabbix server "localhost"

When the trigger fires, the script also does not have time to work

Through the shell, the script works without problems.

The script lasts about 15 seconds.

To test a script comes down to one line:

pjsua --config-file=/etc/pjsua.conf sip:[email protected]
