If your Softphone is on a Windows computer, what must be done for proper registration?

For proper registration of a Softphone on a Windows computer, the built-in firewall must be configured correctly. Firewalls control the incoming and outgoing network traffic based on predetermined security rules, and they can potentially block the ports necessary for the Softphone to communicate with the VoIP server effectively. If the firewall allows SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) traffic through the appropriate ports, the Softphone will be able to register without issues.

Disabling the firewall may temporarily resolve connection issues, but it creates significant security risks by exposing the computer to potential threats and unauthorized access. Therefore, it is essential to maintain a properly configured firewall that allows the necessary traffic while still providing protection for the system. Keeping software and the operating system updated contributes to overall security and performance but does not directly address the registration issue linked to the firewall configuration. Reinstalling the operating system would be an extreme and unnecessary step for resolving registration problems.
