Temperature-dependent polarized Raman spectra of electron-dopedsuperconducting Pr$_x$Ca$_{1-x}$Fe$_2$As$_2$ ($x \approx 0.12$) single crystalsare reported. All four allowed by symmetry even-parity phonons are identified.Phonon mode of B$_{1g}$ symmetry at 222 cm$^{-1}$, which is associated with thec-axis motion of Fe ions, is found to exhibit an anomalous frequency hardeningat low temperatures, that signals non-vanishing electron-phonon coupling in thesuperconducting state and implies that the superconducting gap magnitude$2\Delta_c < 27$meV.
