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

[Tim St. Pierre]

You are seeing the difference between a resale product and a wholesale 
product.

Origination and termination and telecom terms used to describe which way the 
call is going.  Time costs - no matter what.  Even if the provider pays a 
flat rate for their PRIs, the capacity multiplied by the number of minutes in 
a month is the maximum time they have to sell.  Retail packages can provide 
an unlimited number of minutes by estimating the usage of their customers, 
and charging a rate that covers this.  There is generally a user agreement in 
place to enforce their estimates.  Origination and Termination are wholesale 
products where you have unlimited (within practical limits) access under 
their user agreement, because you pay a rate that is proportional to the cost 
of them providing the service.  

In terms of back end, an origination and termination service will often allow 
you to set callerID number, and will allow a peering arrangement that is much 
more conducive to having several incoming DID numbers, and multiple channels 
from the same asterisk machine.
