Blacklist

Sender numbers of incoming faxes and voice mails as well as recipient numbers fpr outgoing messages can be blocked (separatly per service). An incoming call from a blocked number is not accepted.

When a user tries to send a message to a number blocked for sending, he receives an e-mail with a text defined by the administrator.

Therewith, the sending to fax numbers with costs, for example, and the reception of unsolicited faxes can be prevented. For further information, please refer to the ixi-UMS Kernel Configuration.
