ABSTRACT:
Here is described a method, a near end telecommunications terminal and a computer executable software code which allow to perform a telecommunications with a far end telecommunications terminal providing the option of applying a narrowband encoding technique without loosing the benefit of a wideband encoding technique. This is achieved after setting up a telecommunications between that near end telecommunications terminal and the far end telecommunications terminal by applying by the codec from the near end telecommunications terminal a sampling when encoding corresponding to a wideband encoding technique while assembling the resulting timeslots into frames to be transmitted to the far end telecommunications terminal via RTP. Furthermore, the sampled timeslots are assembled when applying the wideband encoding technique according to the parity of the sequential integer number from the sampled timeslots to generate two kind of frames, one with all the timeslots identified by even sequential numbers, the other one with the remaining timeslots identified by odd sequential numbers.
