We know that SIP trunking can reduce the amount of spend for a business. But when you pay for a SIP trunk, what are you actually paying for?
It’s very rarely the SIP trunk itself, which even when you get down to the nitty-gritty of it, is more of a concept than an actual thing you can buy. It can be the amount of time you spend on a call, split into outbound and inbound, with different prices for each. But more often than not, your main consideration is the channels in your SIP trunk.
If you’re looking for a top-to-bottom explanation of SIP trunks, SIP trunking and how they operate, take a look at our ultimate guide.
The Voxbone Definition
In telecoms, a channel is the data capacity required to make one concurrent call on a network. The more channels you have, the more calls you can make and receive.
So if you have 10 people in your business calling customers and 10 customers calling your business to get customer service, you’re using 20 channels.
The Highway Explanation
This is our favorite explanation and one that is used a lot in the telecoms space. The idea is to think of your SIP connection to the voxbone network like a highway. On the highway, you have multiple lanes, each capable of containing a certain amount of cars.
These lanes are like your channels, with the cars being your data. If you start connecting more towns to your highway, you’re going to increase the number of cars, eventually leading to congestion. But, if you add more lanes to the highway, you’re going to smooth out the traffic and avoid jams.
This is similar to adding channels to your SIP trunk. The more data you use to make calls, the more channels you need.
I agree that Voxbone can send me relevant updates to enrich my life from time to time.
So How Many Channels Are There
Well, unlike our highway example, there’s no limit on the number of channels you can have in a SIP trunk. So if you have one million people calling you, you’re going to need one million channels at a minimum.
How Much Is A Channel?
Unfortunately, we can’t speak for all SIP trunk providers as we all have different pricing models (obviously ours is the best), so we can only tell you what we offer ourselves.
At Voxbone we have two pricing models for different types of customer:
Pay-as-you-go for enterprises
You pay a monthly rental fee for your number and then by the minute for your calls.
Flat rates for resellers
Receiving calls is free but you pay a flat rate for the number of channels you need.
We have plenty more information on our pricing page.
