This post is based on our previous post How to add custom action on call to custom extension in FreePBX

In FreePBX, add the following config to /etc/asterisk/extensions_custom.conf in order to add a custom extension 999 that uses System() to run curlon a fixed URL.

[from-internal-additional-custom]
exten => 999,1,Answer()
exten => 999,n,Wait(1)
exten => 999,n,System(curl http://mydomain.com/myurl)
exten => 999,n,Wait(1)
exten => 999,n,Hangup()

Don’t forget to reload Asterisk e.g. using the core reload command from the Administrator menu => Asterisk CLI in order for the changes to take effect.
