I've seen questions about this, but I haven't found an answer. I have multiple Allstar 3 nodes, and all seem drop Echolink after a few minutes. I'm not seeing anything in Asterisk when it happens. It just drops the connection. Echolink on my phone then gives me a message saying the echolink node is requesting a QSO with me. If I tell it to reconnect, it will reconnect for about 15 minutes.
Is there a setting that causes it to disconnect after a period of inactivity?
