Wireshark needs the sampling clock rate to calculate jitter correctly, which makes jitter for dynamic payload types unreliable unless the rate can be learned, for example from the SDP.

As the sampling frequency must be known to correctly calculate jitter it is problematic to do jitter calculations for dynamic payload types.
