Devices in LAN require SIP Trunks?

[Oliver52111]

Hello, I am a starter of using 3CX.

Currently, I installed the 3CX on a Raspberry PI and I enabled to add extensions in the management console. But all the extensions cannot be registered. And some servers such as SIP and Queue Manager also stopped working. Since I just use the devices as lab testing in LAN. Should I set port forwarding to enable SIP server to work so that the devices can talk only using WebMeeting bridge?

I'm not sure what all the extensions cannot be registered means. You haven't said how you are trying to register them, or what you are trying to register. IP phones, 3CX app, web client, etc. But no you don't need any port forwarding for local calling.

Thanks for your response. In my current system, I enable to add extensions on the list and use the verification from the welcome email. But the Windows softphone stuck on the connecting and register failed. My iPhone app keeps 'Waiting for network' when connecting with LAN. Do you have any idea on troubleshooting the above situation?

For the 3CX App, under Extension > Phone Provisioning. Try using FQDN and re provisioning the app, send a welcome email. Open the new config on the app.
