in germany there’s a concept named “call by call” which means that your calls get routed through another provider for cheaper rates by using a calling prefix. (Example:
01067-destination-number) This is especially interesting for calling to mobile networks or international numbers.
These providers do announce the current rate they charge at the beginning of the call, before it starts ringing he destination phone. For some reason, freepbx suppresses this announcement and instead plays the calling tone.
Interestingly, the providers announcement can be listened to in the recordings.
Any tips on how to fix this, so the user can hear the announcement?
