About Voice Service
Response Point supports two kinds of voice services—analog service and VoIP service. Choose the service the best
suits the needs of your business. Both voice services have VoIP technology in common. VoIP allows phone-system
components to communicate using digital signals. Electronic data packets deliver these signals to the software and
hardware that runs Response Point. However, the hardware, setup, and underlying functionality required by each service
is different. For example, analog service needs extra hardware, such as a phone line adapter (which might be built into
the base unit) or an integrated access device (IAD), whereas VoIP service only needs an Internet connection.
Note: A converter (sometimes called an "integrated access device") might have come with the VoIP service you
purchased. The IAD translates between digital signals and analog signals. Although your phone company or other
service provider recognizes this as "VoIP service," it appears to Response Point as "analog service" because the
interface between Response Point and the IAD is an analog one.
Analog service—commonly referred to as "PSTN," "POTS," or traditional phone service—is established through a
landline-based connection using standard phone jacks and cables. To use this voice service, you will need at least
one phone line adapter for Response Point to work. (The adapter might be a detached or built-in device, depending
on the manufacturer.) When an external call comes into the phone system, the phone line adapter converts incoming
analog signals to digital ones, and then sends this data to your IP phones. When you place an outgoing call, the adapter
reverses the process by converting digital signals back to analog ones, and then sends this data over your landline.
VoIP service is established by setting up an account with whichever VoIP service provider you choose. Ask your service
provider any if there are any additional requirements that you might need to consider when you deploy, maintain, and
monitor Response Point with VoIP service. After you configure a VoIP connection, your business can place calls through
an Internet connection, which may reduce the cost of long-distance and international calls. Because this service only
requires an Internet connection, no additional hardware is necessary.
Important: Security is an important factor to consider when selecting a VoIP service provider. When deciding between
available service providers, you should select the company that provides the most secure service.
