Abstract: A method and a call manager node (200) for handling calls directed to a group of subscribers. When receiving (2:3) a request from a caller (202) for access to a first group of subscribers (204) having at least one common characteristic, the call manager node assigns (2:4) first caller-specific temporary group number (A1) for the caller, wherein the first group number can be used exclusively by the caller for calling the subscribers in the first group. The call manager node further sends (2:5) the first group number to the caller in response to the request. The caller is then connected (2:7, 2:9, 2:11) to a subscriber in the first group sequentially or according to a scheme each time the caller dials (2:6, 2:8, 2:10) the first group number. The group is created according to a criteria and the anonymity of the called parties is kept. Call hunting.
