Call Origination, also known as voice origination, refers to the collecting of the calls initiated by a calling party on a telephone exchange of the PSTN, and handing off the calls to a VoIP endpoint or to another exchange or telephone company for completion to a called party.
In the VoIP world, the opposite of call origination is call termination, where a call initiated as a VoIP call is terminated to the PSTN.
The term is often used in referring to a VoIP trunking service that provides the ability for calls to originate on the PSTN and be delivered to a customer's VoIP endpoint. It is often referred to as "DID" (for Direct Inward Dialing) which more properly refers to a service entirely within the PSTN where individual PSTN numbers can terminate on a customer's PBX.
Famous quotes containing the word call:
“When any practice has become the fixed rule of the society in which we live, it is always wise to adhere to that rule, unless it call upon us to do something that is actually wrong. One should not offend the prejudices of the world, even if one is quite sure that they are prejudices.”
—Anthony Trollope (1815–1882)
