Patent ID: 8005071

Claim:
A method of handling Voice over Internet Protocol (VoIP) voice packets communicated between terminals in real time, the method comprising: determining whether a communication payload generated at a Real-time Transport Protocol (RTP) transmitting side is a silence payload or a voice payload; accumulating the silence payload instead of transmitting the silence payload in real time, upon a determination that the communication payload is a silence payload; forming a first RTP packet upon a determination that the communication payload is a voice payload; and forming a second RTP packet upon a determination that a number of accumulated silence payloads reaches a multi-frame limit, wherein determining whether a communication payload generated at an RTP transmitting side is a silence payload or a voice payload comprises: determining that a first communication payload is a voice payload upon a determination that an amount of sound data above a silence reference value within the first communication payload exceeds a threshold value; and determining that the first communication payload is a silence payload upon a determination that the amount of sound data above the silence reference value within the first communication payload does not exceed the threshold value.
