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

Hi, is there anything new since august? I have the same problem with latest FritzBox firmenware and latest FreeSwitch installed (via Quick & Dirty install). FritzBox always sends 30ms in one paket, FS starts with 20 and then switches to 30 (maybe thats the problem?) Calling the Demo IVR at 5000 is (with default options and latest FS) no problem, both uses 30ms ptime, have no idea why. Calling the tetris-demo at 9998 is chopped up, FS using 20ms ptime, FBox 30. Conferences are also choppy. Adding <param name="rtp-autofix-timing" value="false" /> to 1000.xml (account used at the FBox) does not help. Anyone got an idea? Nico
