[asterisk-users] Voip providers and sip origination and termination?

[Yair Hakak]

the thing to remember is that these terms are from the point of view of the
PSTN.
So, SIP origination is Direct Inbound Dial (DID, or DDI in european
parlance) which allows callers on the PSTN to originate calls that end up at
your SIP server.
SIP termination allows calls which originate on your SIP server to terminate
on the PSTN, i.e. to reach a non-voip line.

Voip providers who provide "plans" are bundling 2 distinct services.
Broadvoice, for example, does not expect its users to understand the terms,
and just offers them what used to be called a "phone line" - the ability to
make calls (termination) and recieve them (origination).

i hope this helps,
 yair
