ABSTRACT:
The present invention relates to a method, a node (105) and a network (102) for screening out unfamiliar messages. The invention is preferably applied in a ISUP network. The screening takes place through when a message or a parameter is detected which is not recognized a function is called upon which looks up the message and destination in a table (401, 601). The table (401, 601) is built up and modified by the operator. If the parameter (603) or message (403) and destination (404, 604) are found in the table then the corresponding action (405, 605) which can be, for example, to not forward the message or parameter, is taken.
