Claim:
1. An apparatus for transmitting voice over internet protocol (VoIP) frames, the apparatus comprising: a buffer for reducing a jitter; a controller configured to, if frames are received from a terminal connected with the apparatus through a wireless link, determine whether the buffer is being used; determine whether the frames comprise a voice signal in internet protocol (IP) frame based on a real-time transport protocol (RTP) if the buffer is being used; determine whether it is necessary to use the buffer based on a voice codec used in the frames if the frames comprise the voice signal in IP frame based on the RTP, and search for the buffer if it is necessary to use the buffer; store the frames comprising the voice signal in IP frame based on the RTP in the searched buffer; determine a time interval for transmitting the frames stored in the searched buffer and a service start time for transmitting the frames; and transmit the frames stored in the searched buffer to a device connected with the apparatus through a wired link based on the determined time interval and service start time.
