Understanding SIP Trunk Channels

How to Help Your Customers Understand SIP Trunk Channels

Innovation in modern telecommunications would make Alexander Graham Bell, father of the industry, proud.

For those of us dealing with the rapid advances, though, all of the change can be difficult to navigate.

And if it’s difficult for IT professionals, just think how difficult it must be for customers who, a few years back, thought there was no need to switch from their dial-up Internet connections.

While we’re obviously way past justifying VoIP as a technology, often times convincing customers that cloud phone services like SIP trunking are the best thing for them can be difficult due to them not understanding and technical jargon.

Here’s how you can have a breakthrough just like Mr. Bell.

Before There Was SIP: The Old School Way, Traditional Telecommunications

When explaining SIP channels, it helps to start at the beginning.

We’re not going as old school as Alexander Graham Bell’s telegraph, but for as old as the Public Switched Telephone Network (PSTN) feels, not so long ago it front and center for most of your customers.

(Some may even be holding on to it like a classic car, unaware that there’s no appreciating value left.)

Back then, telecommunications systems were all hard-wired and circuit-switched. A physical trunk would be run from the central office to your facility. Within each trunk were lines (or channels) that could be accessed for calling.

Everything was physical and, while the physical wires and lines could get confusing, at least they were tangible. This is where the naming for SIP trunking and the concept of SIP channels originates from.

Enter the IP Communications: A Brave New World and Virtual Everything

The new world of telecommunications can be scary, we’ll give you that. Seeing is believing, they say, and a phone system that is unseen or virtual can be hard for your customers to wrap their minds around.

In the old world, you could drag a customer over to closet. You could show them a trunk and the channels.

This made showing what you’re selling much easier.

With SIP physical trunks are no longer necessary to connect a phone system to a voice network. Instead your customer can connect virtual trunks, (SIP trunks) and based on the number of simultaneous calls they need to make, get up to 48 channels per trunk.

A SIP trunk then is the virtual container for your virtual lines. This makes the best way of describing SIP channels to your customer as the number of paths for simultaneous calls or lines of calling needed.

Something that should be easy for them to understand.

Other Resources for Understanding SIP Channels

In addition to a basic understanding of SIP, learning about DIDs and the benefits of SIP trunking, knowing the bandwidth requirements for SIP trunks, will help you explain to your customers all that’s involved with SIP trunking services.

Good luck and happy selling!
