Allstar node running Hamvoip software on raspberry pi 3b+ working without problems, when attemping to connect Echolink node using android phone Dvswitch reports node connected then node disconnected. Echolink. conf file setup with echolink wiki instructions.
Check that you have chan_echolink enabled to load in /etc/asterisk/modules.
Switched on this morning and echolink is working perfectly, it is very strange as nothing has changed.
