Identifying information associated with a user under surveillance is received. A first intercept is provisioned on a first network element to intercept the data traffic according to the identifying information. A database is queried based on a login identifier associated with the user. A query result is received from the database. The query result may include a network element identifier and circuit information associate with the login identifier. A determination is made as to whether the network element identifier contained in the query result is the same as a network element identifier contained in information of record. In response to determining that the network element identifier contained in the query result is different from the network element identifier contained in the information of record, a second intercept is provisioned on a second network element to intercept the data traffic according to the network element identifier contained in the query result.
