A method and device for automatic interaction, for example a market survey, with a number of subscribers (110-117) in a telecommunication network (120), such as a public switched telephone network (PSTN). A customer (100) requests an automated interaction, such as an advertisement or a market survey, with a group of subscribers, a target group, of the telecommunication network. The subscribers of the target group are selected by predetermined criteria, such as age and/or area of residence. The subscribers of the target group are called and automatically interacted with by the telecommunication network. A record is kept by the network of which subscribers could be reached within certain predetermined constraints, which of the subscribers that could be reached that actually completed the interaction and which did not. The results of the automated transactions are reported to the customer (100).
