Abstract:
1. A method for providing telecommunications between a near end and at least a far end telecommunications terminal, each telecommunications terminal having a codec, the method comprising: setting up telecommunications between the near end telecommunications terminal and the far end telecommunications terminal; applying a wideband encoding technique codec at the near end telecommunications terminal to sampled timeslots; assembling the sampled timeslots when applying the wideband encoding technique according to the parity of their sequential integer number to generate two kinds of Real Time Protocol (RTP) frames to be transmitted to the far end telecommunications terminal via a packet switched network using Real Time Protocol, one with all the timeslots identified by even sequential numbers, the other one with the remaining timeslots identified by odd sequential numbers; transmitting to the far end telecommunications terminal each of the two kinds of RTP frames via a different specific RTP stream corresponding to a narrowband channel, the two kinds of RTP frames having timestamps related to each other using the same reference clock, wherein each timestamp relates to the mean value of the RTP frame payload time of a RTP frame of the first kind and a RTP frame of the second kind; and if applying a wideband decoding technique at reception of the two kinds of RTP frames, then reassembling the timeslots according to the initial sequence.
