good morning everyone, for about 3/4 days I have not been able to associate Micollab +MBG users on terminals (Android, ios), I noticed that when I move to Mivoice Border Gateway -> Troubleshooting -> Diagnostics -> Connectivity test , the test on port 5061 TCP/TLS fails, could this be the problem?
instead when I move to this screen, it doesn't assign me the user at extension 8000
Can you give me a tip please?
