What is the first step in prequalifying a new customer's telephony service?

The first step in prequalifying a new customer's telephony service is to locate all telephones and jacks. This step is crucial because it allows the technician to understand the existing infrastructure within the customer's premises. By identifying where telephones and jacks are situated, the technician can determine the feasibility of connecting new services and ensure that the customer has the necessary wiring in place for their telephony needs.

Locating telephones and jacks also helps in troubleshooting any existing issues and aids in planning for the installation of new equipment or services. This foundational knowledge enables the technician to provide a more accurate assessment of service options and address any potential complications that may arise during installation. This process is integral to providing efficient and effective service to the customer, setting the stage for the rest of the installation or service process.
