Title:
会議電話を確立するための方法およびシステム
Document Type and Number:
Japanese Patent JP4874994
Kind Code:
B2
Abstract:
A method and arrangement for establishing a conference call from a mobile station in a call centre environment. A user may choose conference call participants from his mobile phone, and a client application in the mobile phone will communicate relevant parameters to the call centre server, which will then call the conference initiator and other participants via the gateway server. The calls are handed over to the gateway server, which will digitize each call to an audio and/or video stream, typically an RTP stream. The streams are relayed to a computer where the streams are combined to form a successful conference call. The conference call is then recorded to a data file on the computer, and may be sent to participants or stored to a database with relevant metadata. The network infrastructure of the telecommunications network operator need not be consulted, nor is there any need for additional hardware.
