After much trial and error issue is related to firewall settings. Opening ports 16384 - 32768 enabled silence detection to work as expected. On Thu, 23 Aug 2018 at 17:02, vidor via FreeSWITCH-users < freeswitch-users@lists.freeswitch.org> wrote:

If I dial to an internal extension the wait_for_silence and detect_silence commands are working fine.

However if dial out through an external gateway to PSTN I don't get expected results. Silence is always detected, even if there is voice speaking. I can detect DTMF commands fine...

Is there any known issue or parameter required on the gateway in order to detect the audio / silence.

Thanks in advance!
