Voice entities

For information about voice entity configuration, see "Configuring voice entities", "Configuring VoFR", and "Configuring customizable IVR."

There are four kinds of voice entities: POTS entity, VoIP entity, VoFR entity, and IVR entity.

• A POTS entity corresponds to the local telephone (or PSTN) side. POTS entity configuration associates a voice subscriber line on the VoIP gateway with a local telephone. The POTS entity configuration also implements the binding between telephone numbers and voice subscriber lines.

• A VoIP entity relates a call entity with a routing policy. Compared with the POTS entity, the VoIP entity corresponds to the IP network side. VoIP configuration implements the binding between telephone numbers and destination addresses (IP addresses or server addresses).

• A VoFR entity is used to transmit voice data over a frame relay network.

• An IVR entity is used to set a customizable interactive voice response system.
