Abstract
The provision of subscriber service features is one of the tasks of exchanges in classic TDM networks. This includes e.g., announcements and interactive responses. According to the prior art, these announcements and interactive responses are either provided by peripheral devices of the exchange which are equipped with the appropriate function or by external announcement and interactive response systems. The latter are provided either in TDM networks with proprietary interfaces or in packet networks with standardized interfaces. The invention solves the problem of providing the service for classic TDM networks by providing that the known packet-based method for controlling an external system for providing announcements and interactive responses is transferred to an exchange located in the classical TDM network. In particular, this enables the protocol used to control the external announcement and interactive response system, which was originally standardized as a signalling protocol for controlling a media gateway, to be used.
