[Freeswitch-users] Choppy voive in conference from fritzbox to freeswitch (ptime:30 msecs)

auto-adjust will automatically switch the IP the RTP is being sent to based on the received packet's IP header. autofix timing mesures the received payload size and compares it with how much "<ptime> ms " is supposed to take. If there is a difference it thins the device is broken (a lot of UAs lie about their ptime in the SDP) and adjusts the codec's ptime in order to interop.

To be the equivalent of your patch, it would have to be set to false.

Out of curiosity, what codec is being used by fritzbox when the problem occurs?
