What should a skilled VoIP installation technician inquire about to prevent device issues?

A VoIP installation technician should focus on inquiring about devices connected to the POTS line to prevent potential device issues because these devices can have a significant impact on VoIP performance and functionality. Understanding what is connected to the POTS (Plain Old Telephone Service) line helps the technician assess if any legacy devices could interfere with the new VoIP setup. For example, traditional telephones or fax machines that are still operational on the same line might lead to issues such as call quality degradation or disruptions in service due to voltage fluctuations or line noise.

The technician's knowledge of what POTS devices are in use allows for better troubleshooting and configuration of the VoIP system, ensuring that any necessary adjustments or upgrades can be communicated to the customer. This proactive approach enhances overall service reliability and user experience, as it clarifies any potential compatibility concerns and prepares the installation for a smooth transition to VoIP technology.
