VoIP Configuration (continued)
After restarting, the DVG-5121SP will automatically connect with the SIP VoIP service
to which the entered user account is subscribed. Look at the Phone LED or listen for a
dial tone by taking the phone off the hook to check if VoIP phone service has been
successfully initiated.
After correctly entering the VoIP settings, users can use SIP VoIP phone service
without any further need for changing or adjusting the settings to make IP phone calls.
