[Freeswitch-users] sip stack problem in fsw

[JRichey]

I'm in a similar situation where I need to disable VAD because the other end
will disconnect the call if the RTP stops.  I've tried the setting Anthony
suggested as well as several others I've found on the wiki, but I've not
been able to get it to work.  The variables I've been trying are listed
below.

suppress-cng
suppress_cng
rtp_disable_vad_out
rtp_disable_vad_in
bridge_generate_comfort_noise
send_silence_when_idle


For my test calls I'm just playing back sound files with sleep in-between
them and I see no RTP when calling sleep.  I'm using tcpdump and wireshark
to analyze the calls.

Thanks for the suggestion -- unfortunately it did not work -- I put it
in the internal profile, but it seems to have  had no effect.  I did see
that the cng packets were 0.

Your life is like a penny.  You're going to lose it.  The question is:
How do
you spend it?
