Hi guys. I recently stumbled upon a problem i've yet to solve. The setup is this: We host a 3cx server for a customer of ours. It has worked just fine for a couple of months. Some weeks ago some users are having problems with outgoing calls drops after 32 seconds. Incoming calls works fine. They are all using 3cx softphone. If I tell the users having problems to just restart their softphone the problem goes away for some time but it allways comes back. I've installed all the latest updates and the softphones are the most recent versions. Firewall checker shows all green. Any suggestions?
