I would like to add a messages to the caller on certain outbound routes before the number is dialled.
As an exemple, if someone is calling a “premium-rate numbers”, I would like to warn the caller with a message like " be aware you are calling a premium number that costs XX cts per minute".
So, all numbers called starting 09xxx (here in CH), the caller will get that message from a specific outbound route with the right dial pattern.
Any easy way implementing this with a standard FreePBX distro ?
Thanks in advance
