Telephone tones such as dialing tones and busy or engaged tones differ in different countries and in traditional telephone networks it has been possible to deal with this because national telephone networks have been used. However, with the advent of next generation communications networks in which telephone services are transmitted over a packet network, a need has arisen to manage telephone tones in a more sophisticated manner. To address this, a tone service provides telephone tone information to tone recipients such as media gateways, session initiation protocol (SIP) phones and virtual media gateways. In the event that a new tone recipient is added to the packet network, the tone service is able to automatically provide appropriate telephone tone information to that new tone recipient. Similarly, if telephone tones need to be upgraded or rolled back, the tone service is able to automatically provide appropriate telephone tone information to each of the tone recipients.
A method of providing tone information to at least one of a plurality of nodes in a packet network over which telephone services are transmitted, each of said nodes having one or more attributes comprising one or more of node location, node type and node manufacturer, said method comprising the steps of:
A method of operating a tone recipient in order to obtain tone information said method comprising the steps of:
A tone recipient arranged to obtain tone information, said tone recipient comprising:
A tone server for providing tone information to at least one of a plurality of nodes in a packet network over which telephone services are transmitted, each of said nodes having one or more attributes comprising one or more of node location, node type and node manufacturer, said tone server comprising:
A computer program stored on a computer readable medium and executable by a tone server in order to provide tone information to at least one of a plurality of nodes in a packet network over which telephone services are transmitted, each of said nodes having one or more attributes comprising one or more of node location, node type and node manufacturer, said computer program being arranged to control the tone server such that:
A method of providing tone information to at least one of a plurality of nodes in a packet network over which telephone services are transmitted, each of said nodes having one or more attributes, the packet network having a plurality of tone servers, said method comprising the steps of:
