CALL RECORDING METHOD, DEVICE AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/183774
Kind Code:
A1
Abstract:
Disclosed in the present invention is a call recording method, comprising: receiving, by an IP phone terminal, a voice signal from a local-end user and converting the voice signal to a first media stream; receiving, by the IP phone terminal, a second media stream transmitted from an opposite-end call device; performing, by a digital signal processor(DSP) module of the IP phone terminal, sound mixing of the first media stream and the second media stream to obtain a third media stream; and transmitting, by the IP phone terminal, a third media stream to a recording server to be recorded. The embodiment of the present invention can reduce DSP media resource occupation of the sound mixing in an IP-PBX gateway, thus meeting the demand of point-to-point recording performed simultaneously by large-volume users.
