What is Business VoIP

Business VoIP is a solution businesses use to converse with customers, make sales, and collaborate with their teams on calls over an internet connection at a low per-minute rate.

Although Voice over Internet Protocol (VoIP) lets you make calls over the Internet, it is used on a standard phone. Businesses link their phone network to the VoIP adapter, which is then connected to a WiFi router to start making calls via a strong internet connection. (Learn how to set up VoIP in easy steps.)

Also, a business VoIP service provider offers more than just basic calling capabilities. They provide advanced features that make business communication friction-free and productive.

Are you Wondering whether it is mandatory for both the caller and the recipient to have VoIP for successful calls to happen? Well, calls can happen even if the VoIP is not enabled for the receiver. VoIP calls to a regular line phone number are converted to regular signals with zero lags or quality issues. Also, the VoIP system works well on computers, laptops, tablets, smartphones, and desk phones.

Now relying on the best VoIP service providers UK is a great choice for all business sizes, but as large companies have to cater to high call volumes, there’s an option to use SIP trunking, an element of VoIP. It allows your servers to efficiently handle large call volumes without lag or compromising call quality.

So, you see how VoIP services UK can take your business phone calls to the next level–more reliable, efficient, high-quality, and cheap (compared to the standard line).

1. Minimal call costs

Regardless of the VoIP providers you opt for, VoIP phone systems are known to reduce costs. The percentage of cost reduction varies with different VoIP system, but ideally, businesses save an average of 30-50%.

Here’s how VoIP is way cheaper than traditional phone systems:

  • A traditional phone system needs PBX hardware and handsets that cost thousands of pounds, whereas, with VoIP phone systems, you have to pay the monthly/yearly fee of the plan you buy.
  • Using a traditional phone system requires connecting the ISDN line to each agent’s desk, which is expensive. Not just that, to add new users to your phone system, you have to attach a cable to the PBX, restricting your flexibility. All these issues are solved with a decent VoIP provider UK as it requires no external cable or hardware, just stable interment connection works.
  • Traditional phone systems cannot be used without the hardware and may face several issues. Now both of these things add up to maintenance costs. You can eliminate this with VoIP, as it has neither hardware nor maintenance charges to increase your expenses.

2. Flexibility to take business calls from any location

VoIP system does not need any physical phone to make business calls as it runs on the internet. This eliminates needing to be at the office whenever you need to talk to customers, prospects, or teammates. That’s how VoIP providers enable you to work from home or anywhere at your convenience.
