We present far-infrared reflection spectra of Pb_{0.95}Mn_{0.05}Te single crystal doped with gallium between 10 and 300 K. The analysis of the far-infrared reflection spectra was made by a fitting procedure based on the model of coupled oscillators. Together with the strong plasmon-phonon coupling we obtain three local modes of gallium at about 122 cm^{-1}, 166 cm^{-1}, and 192 cm^{-1}. The position of these modes depends on impurity center charge, and their intensity depends on temperature.
