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:
“With the holders holding my hand nearing the call of the bird,
Comrades mine and I in the midst, and their memory ever to keep, for the dead I loved so well,
For the sweetest, wisest soul of all my days and
lands—and this for his dear sake,
Lilac and star and bird twined with the chant of my soul,
There in the fragrant pines and the cedars dusk and dim.”
—Walt Whitman (1819–1892)
