What Is a VoIP Number?


VoIP stands for Voice over Internet Protocol. A VoIP number is a virtual phone number that allows users to make and receive phone calls over an internet connection (WiFi or data). Phone numbers from mobile network operators are associated with a physical telephone line or a SIM card. On the other hand, VoIP numbers are not tied to anything, making them highly portable and flexible. 


VoIP numbers often offer a range of features, such as call routing, voicemail, call recording, and more, making them a popular choice for cost-effective and versatile business communication solutions. 


Benefits of Using VoIP Numbers


There are many benefits to using VoIP numbers. Especially for businesses needing a company phone number. Here are the top benefits of using a VoIP number for business: 


  1. Cost-effectiveness: Subscribing to a VoIP phone service is significantly cheaper than with traditional carriers. VoIP services often offer lower calling rates, especially for international calls. This leads to significant cost savings for businesses, especially those with high call volumes.
  2. Scalability: Tech scalability is important for growing businesses. VoIP systems are highly scalable as businesses can easily add or remove lines as needed. This is difficult to do with traditional solutions such as landline desk phones, where lots of hardware is needed. The flexibility that VoIP provides is particularly beneficial for growing businesses or those with fluctuating call volumes. 
  3. Mobility and flexibility: VoIP numbers are not tied to physical locations. Instead, they’re stored in a cloud network. Enabling employees to make and receive calls from anywhere as long as they have a stable internet connection. This mobility allows for remote work and the ability to stay connected while on the go. 
  4. Advanced features: VoIP systems offer a wide range of advanced features that can enhance business communications. These include call forwarding, auto-attendant, call recording, and software integrations e.g. CRM systems. Taking advantage of advanced calling features helps businesses to create a better communications experience for both customers and employees. 
  5. Analytics and reporting: Some VoIP providers may offer detailed call analytics and reporting. This provides businesses with valuable insights into call volumes, call durations, and other metrics. Having access to this data is key as it allows you to determine your strong and weak points, empowering a data-driven approach to business growth. 
  6. International presence: It is easier to obtain international numbers with a VoIP service than through traditional routes. International numbers allow businesses to establish a local presence in global markets without needing a physical office. This is advantageous for expanding into new markets and customer service. 
  7. Integration capabilities: VoIP phone systems can integrate with other business applications and tools such as customer relationship management (CRM) systems. This creates streamlined workflows which increase efficiency and productivity. It’s particularly helpful for customer service teams or sales-based teams. 
  8. Better Security: Traditional phone lines can be disrupted by environmental changes. VoIP numbers, on the other hand, are not tied to physical infrastructure and can be quickly rerouted to alternative locations or devices, ensuring uninterrupted communication during emergencies. This is important for keeping company data secure and ensuring company information doesn’t get lost.


How to Obtain a VoIP Number


The process to get a VoIP number is more straightforward than you may think! Follow these easy steps to get a VoIP number: 


  1. Do the research: It’s important to research the options available before you sign up. You’ll need to take into account your needs, budget & pricing, features available, and the type of number you need e.g. mobile, landline, or international. This allows you to choose a provider that best provides all that you’ll need, saving you time and money later down the road.
  2. Get in touch with your chosen provider: Once you’ve chosen a provider, you may wish to get in touch with them if you have any questions or additional requirements for your VoIP number e.g. specific features. It can be helpful to speak with a member of the team to help determine if they’re the right fit for your specific needs.
  3. Sign up for an account: Be sure to get a grasp of the types of pricing plans offered. Many VoIP providers offer contracts for a minimum of 1 year.

Alternatively, you may wish to find a provider with a subscription model of pricing whereby you pay monthly and aren’t locked into a contract. 
  4. Choose your number: Some providers may give you the option to choose the VoIP number you’d like to use. However, most providers will assign you a phone number.

  5. Set up your VoIP Phone: VoIP numbers can be set up with VoIP desk phones or your mobile phone. If you opted for a VoIP desk phone, you’ll need to get these delivered and your provider should provide instructions on how to set these up as well as any equipment you may need. If you opted to use VoIP on your mobile phone, you’ll be prompted to download the provider’s app following sign-up. You’ll be provided account details which allow you to log in to the VoIP platform. With both VoIP phones and VoIP on mobile, you’ll need to configure your settings such as call forwarding and voicemail and then you should be good to go!
