System information

In Caller Prefix, you can place only one prefix.
Tech prefix can be empty string, asterisk (*) or 3 digit length number.
Called prefix can be one prefix (with any length) or a list of prefixes with 3 or 4 digit separated by comma.
*Tip: you don’t need to enforce traffic sender rights by routing. The routing can be done as generic as possible for example by specifying only Called
Prefixes (Leave the other direction option blank or ‘*’). Rights can be enforced by setting “Enabled Prefixes” for all Traffic Senders
