The technology of SIP trunking may sound a bit overwhelming but the truth is the concept is very easy to understand and pretty much everything you need to know about it is self explanatory, there are just a few considerations to bear in mind and you can enjoy its money saving benefits in an instant.
How it works
To make everything as simple as possible, a SIP trunk diverts your phone calls through the internet instead of using bundles of physical copper wires and uses no PRI (primary rate interface) and less PSTN (Public Switched Telephone Network) by doing so cost are significantly reduced. Furthermore it is also one of the most favorable way to centralized communication streams by many businesses around the world.
Things you need
There are four main components you need to flawlessly deploy the technology first is your Internet telephony service provider which will create the connection to regular telephone lines, second is your internet connection which is the bread and butter of the system, third is a border session controller that connects your PBX to your service provider and lastly is an IP based PBX.
How do you save money?
If you make a quick internet search for SIP trunking countless of search results will pop out discussing its advantages and all but to sum everything up the main advantage of a SIP trunk is its ability to reduce your phone bills by half mainly because of the cheaper dial rates, reduced line rentals cost and PRI elimination.
Fast set up and Maintenance free
On average it only takes about 10 business days for the system to be fully functional and investments are on a minimal side since it sits in the cloud subsequently maintenance happens in the cloud or in a remote server level so you need not to worry on that part.
How is the call quality?
Primary concern of business owners who are new to VoIP is the call quality, before any VoIP service are struggling to capture the market because of poor bandwidth but today innovations in internet connections paved way for VoIP to take the center stage of the telecommunication industry and just about anyone can access reliable internet connection especially with the introduction of the 4G network.
Is there any lock in periods?
It varies, but most VoIP providers offer no lock in contracts unlike traditional carriers that will oblige you to sign a year contract at the minimum.
