i want to add pin conformation for outgoing call in asterisk 13 before i implement this dial plan with asterisk 11. now i try it with asterisk 13. asterisk 13 in call always hangup

/etc/asterisk/extensions_custom.conf

this is the error when i try to run this

error with debugging

how i fix this error or another way to do this

I'm not a PHP expert, so I won't fix your script, but I think I have a workaround. You can use "Authenticate" application to achieve that. It basically ask caller to introduce a key to continue with the dialplan. [from-outgoinpin]

exten => _.,1,Authenticate(<YOUR PIN HERE>) same => n,whatever you want

Here the docs: https://wiki.asterisk.org/wiki/display/AST/Application_Authenticate

Hope it helped :)
