Have a message read aloud for a phone call
ISDN provides the calling party and is available from many routers. Have a configurable message read aloud by this device when a call arrives.
The message is configured of three parts: First a prefix from a configurable list of prefix messages. Then a message for the exact number actually calling and then a suffix from a configurable list of suffix messages.
Example:
"Hello " from the prefices.
"John " for the phone number (e. g. of John).
"is calling" from the suffices.
In total "Hello John is calling".
The current implementation allows for 16 prefix and suffix messages and 64 number specific messages. If the number is unknown the message "Unknown number" is read.
