Abstract
A method for providing real time indicator of voice transmission quality in a Voice over Internet Protocol (VoIP) network is disclosed. The method allows to receive, at regular time interval during a call, a digital signature from a source call device. The received signature is compared to a referential signature stored on the destination devices, and in case the received signature falls out of the referential signature, a quality indication message is transmitted back to the source call device.
