hello, I use wireshatk to capture RTP streams and restore them. But the waveform is in yellow background and there is no waveform curve.After I click play button, there is no voice. My wireshark version is 1.6.4. Thank you.

Then the codec used is probably not supported. Only PCM A-law and PCM u-law are supported by default.

Thank you. I changed the codec and it worked. The previous codec is GSM. However, there are some vertical yellow lines marked "w" in waveform.
