16.11 CONNECTION TO A DIGITAL LINE OR VOIP -1
It is not technically possible to directly connect a VoIP hybrid phone directly.
You must insert between VoIP and Telephone Hybrid a A.T.A device
16.11.1 What is a A.T.A device?
An Analog Telephone Adapter (ATA) (Analog Telephone Adapter) is a device used to connect one or more standard
analog phones in order to use them with other systems such as the transport of voice over IP (VoIP)
The ATA is provided by some VoIP providers in order to allow the user to connect their phone from the cable pulling the
traditional telephone company. In this case it is possible that the ATA is locked and therefore can only be used with the
VoIP provider from whom you purchased it.
An ATA typically has at least one port where you can connect a telephone (normally a RJ11) and one Ethernet port
(normally a RJ45) to connect to a LAN connected to the Internet. More complex models can have multiple telephone
ports for phones or ISDN PBX and an additional Ethernet port to which you can connect other network objects.
The device is programmed with a dedicated number, which adds a second phone line to the home. Two numbers, the
desk phone and the ATA device, share the same line. When a call comes in, the ATA adapter rings even when it is
directed to the telephone line. When you dial a number, based on the prefix, the call is routed to a fixed line or the
Internet.
