To make calls with PhonerLite, you always need SIP account credentials. These credentials can come either from an Internet VoIP provider or from a local IP-PBX in your own network.
The recommended way is to enter these credentials through the wizard: open Configuration and click New. The wizard guides you through the initial setup step by step.
Your provider usually supplies the required account details:
Prefer entering this information through the wizard via Configuration and New. Alternatively, you can set the values manually under Configuration > Server and Configuration > User.
If you are using a local phone system (IP-PBX) in your LAN, use the SIP extension credentials created on that system. You still need the PBX server address, username, and password.
Once registration is successful, you can place outgoing calls and receive incoming calls directly in PhonerLite.
