[Freeswitch-users] VAD + session record

Hello, We have a problem with session recording if VAD is turned on. if there is no RTP there is no data written to the file so the it becomes shorter then the speech. I tried brigde_generate_comfort_noise=yes to generate the noise, but i think it doesn't work. I don't hear the noise only the total silence if VAD is turned on. Should it generate noise if there is no RTP packets (as fas as I understand, it should) or only if FS receives CN RTP packets (audio_bridge_thread check SFF_CNG flag on frame, but I don't really understand what does it mean. It must be CN packet? ) Should FS send CN packets when VAD is turned on, or not? Thanks, Tamas
