Dial 0 for external dialtone

Does anyone know how you can configure freePBX so you can dial 0 and hear the external dial tone?

just checking because im trying to recreate a true 1980s mechanical PBX

thanks B.

What capabilities of FreePBX do you want to retain after the simulated external line?

Howdy @ringedseal13 - Welcome to the forum and thanks for using FreePBX!

What are you using as the dial out? Do you have a SIP service or are you trying to grab a POTs line from say an FXO port?
