I'm trying to change default frame size from 30 to 40 bytes for G729 (commercial version) but setting correspondent codec prefs to G729@40i (vars.conf) gives no effect. Codec still starts with 30 bytes frames: 2011-09-15 19:00:37.538174 [DEBUG] switch_ivr_play_say.c:1302 Codec Activated L16@8000hz 1 channels 30ms Is it possible to do that with mod_com_g729 ? Thanks, Mike
