Caller ID format settings can be adjusted in "Trunks" section. Different caller-id settings can be specified for each trunk. Caller ID formats:
RAW - caller-id is sent as received from originating side.
E.164 - caller-id is sent in format (Country code + Area code + Number).
LOCAL - caller-id is sent in local format (Area code + Number).
“CLI Prefix” tab allows adding a prefix to caller-id. For example, if symbol “+” is specified, it will be added at the beginning of each caller-id received.
