it's nothing to do with vad, it's simply how FS works.

It's a waste to encode and send zeros into the channel while it's recording.
Also, It's unreasonable to have such a short timeout.

I understand it's not your fault, I am just letting you know.

It would be possible to add a patch to create a channel variable like
NDLB_waste_bandwidth_while_recording or something but it does not exist today.

Hi all,

until previous message I have tried all combinations of VAD settings and
 VM recording format and still no luck:
using ngrep I can't see any RTP packetes going from FreeSWITCH during VM
recording => calls are dropped by my TSPs after few seconds.

Could you, please, point me to some other direction where should I
experient? Or is it desired behaviour of FreeSWITCH?

Best regards,
