This VoIP trunking service may originate on the PSTN but it will be delivered to a customer's endpoint. It is also aptly referred as Direct Inward Dialing or DID implying a service entirely within the PSTN where the individual PSTN numbers are terminated at a customer's PBX.

Technically call origination or voice origination is a process of collecting calls initiated by a calling party on a PSTN and handing over those calls to a VoIP endpoint or a telecom company for its completion to called party. The reverse process is call termination where a call initiated as a VoIP call is terminated to the PSTN.
Choose the Provider
With increasing competition, a business must select its origination provider strictly on the basis of their credentials, footprint and DID features. The most important criteria are
• Mode of purchase usage (per min or per port)
• Identifying MRCs (Monthly Recurring Costs)
• Identifying NRCs (Non-Recurring Costs)
• Content of a contract
Before selecting a wholesale DID origination provider decide how to purchase usage services. It can be,
• By the Minute
• By the port
Per minute model: A per minute model bill means pay only for what you use or the minutes you used.
Per port model: Purchase only that many ports to cover the calls on the basis of concurrent calls at peak hours. This will check wastage of dollars by not purchasing too many ports.
As per industry statistics, an average residential end user consumes 500 minutes per month and the business user consumes 1000 minutes a month. So, based on a metric of $.0035/minute for 500 minutes there is a cost of $1.75 usage per residential end user.
Choosing the right model would need better telecom experience. It will require more management to maximize port utilization. In terms of lines to ports usage it is a 2-to-1 ratio. Established and experienced organizations purchase service in such a way to manage port aggregation and costs fruitfully. The rule of thumb is that if per port aggregation is less than 5,000 minutes per port, it is good to go for a per minute model.
