Method for controlling recorded announcement and interactive voice responses in packet networks
View Patent ↗The invention relates to a method for controlling recorded announcements and interactive voice responses for calls made outside an exchange, using a packet network (PN), by means of peripheral equipment (LTG) of a switching system, which does not provide any HW-oriented tasks for its interface system controlled by switching technology, whereby peripheral equipment (LTG) with virtual ports is defined. The method is characterised in that resources for the recorded announcement and interactive voice response function are provided by an external device, that the peripheral equipment is provided with virtual recorded announcement and interactive voice response ports, that an interface exists between the peripheral equipment and the external device and that the external resources can be used in relation to a specific port by the switching system.
1. A method for controlling announcements and dialogs for connections carried outside a switching center via a packet network, by peripheral devices of a switching system, comprising:
providing resources for the announcement and dialog by an external device, which is located in the packet network;
providing the peripheral devices with virtual announcement and dialog ports, where the peripheral devices are included in the switching center, a control interface exists between the peripheral devices and the external device, and external devices can be utilized in a port-specific manner by the switching system; and
imaging failures or renewed availability of announcement and dialog resources as a temporary block of virtual announcement and dialog ports on peripheral devices with announcement/dialog functions.
2. The method according to claim 1 , wherein the operating system and the back-up technology of the peripheral device with virtual ports allow quasi-parallel processing of n virtual peripheral devices, whereby each virtual peripheral device can be addressed by a respective logical address by way of the message interface of the physically assigned peripheral device.
3. The method according to claim 1 , wherein packet-based transport of the working data stream for announcements and dialogs takes place in the direction of the packet network.
4. The method according to claim 1 , wherein the internal interfaces to the peripheral device, with announcement and/or dialog function, are maintained.
5. The method according to claim 1 , wherein administration internal to the switching system takes place as an announcement/dialog port on a network transition device.
6. The method according to claim 1 , wherein control protocols for network transition devices are provided with announcement/dialog-specific elements.
7. The method according to claim 1 , wherein origination-dependent routing is provided for selecting an announcement and/or dialog resource.
8. The method according to claim 1 , wherein different IVR functionality at different external systems is taken into account by bundle formation of virtual ports having a same function.
9. The method according to claim 1 , wherein the announcement and dialog resources can be used in undoubted and doubled peripheral devices.
10. The method according to claim 1 , wherein standard announcements, individualized announcements and dialogs are supported by DTMF, voice or dial impulse input.
11. The method according to claim 1 , wherein the packet network is structured as an IP network.
12. The method according to claim 1 , wherein the packet network is structured as an ATM network.
13. A system for controlling announcements and dialogs for connections carried outside a switching center via a packet network, by peripheral devices of a switching system, comprising:
resources for the announcement and dialog by an external device, which is located in the packet network;
virtual announcement and dialog ports provided to the peripheral devices, where the peripheral device are included in the switching center;
a control interface between the peripheral devices and the external device, wherein external devices can be utilized in a port-specific manner by the switching system; and
failures or renewed availability of announcement and dialog resources are imaged as a temporary block of virtual announcement and dialog ports on peripheral devices with announcement/dialog functions.
14. The method according to claim 1 , wherein peripheral devices do not make any hardware-oriented tasks available for the peripherals assigned to them by switching technology, thereby defining peripheral devices with virtual ports.
