I am running Asterisk 13.38.0 and using Conf Bridging.. one way audio. When the conf hangs up – “sometimes” all the endpoints do not hangup. I have rtptimeout` but that does not seem to help hang up the channel.

Is there something else I should be setting to also ensure channels hangup ?
Is there a way to ensure if “no” audio on a channel – it hangs up ?

Thanks,

Jerry
