How to automatically broadcast messages over W-PA at the fixed time

Dialplan configuration 

You can use the following Custom application to play back pre-recorded messages:

• Custom application -> Page(Local/911@pbxservices,nA(00000/WPA))

Where:

911 - Feature Code "Paging" + Paging Group ID where the device is present

00000/WPA - pre-recorded message

Cron file setting up

• Connect via SSH and run the following command to edit crontab file or create a new one if it doesn't exist:

crontab -e -u root

• In the cron file, specify the time at which pre-recorded messages have to be played back (1 line) and run the command applying API Originate (2 line) :

*/2 * * * * my-script.sh
curl -u admin:password -k -X POST --data-urlencode "channel=Local/112@users" --data-urlencode "exten=112" --data-urlencode "context=users" --data-urlencode "priority=1" --data-urlencode "callerid=\"Announcer\" <112>" https://127.0.0.1/api/v1/Originate

Where:

*/2 * * * * my-script.sh - the string that runs the next command every 2 minutes. More information about crontab syntax: LINK

admin:password - admin credentials of your PBX

112 - the extension number of W-PA user

users - Dialplan procedure where the called number is matched

Announcer - the name of W-PA user
