What’s the difference?

Traditional phone numbers versus Virtual phone numbers

Even though virtual phone numbers and regular phone numbers work the same, there are key differences between the two. First, area codes don’t really matter when it comes to VoIP phone systems. Unlike regular phone numbers, virtual ones work independently of location. This means you’ll be able to choose a phone number with any area code you choose.

Second, landline phone numbers are linked to a specific device, usually a landline phone you can have at home or in your office. Virtual phone numbers can be linked to many devices, which allows users to make voice calls not only from a landline but also from a smartphone or a computer. All you need to make the call is the virtual phone number! This provides businesses with greater flexibility and freedom of use, which is key in today’s world.

Virtual phone numbers will allow you to measure your marketing efforts by tracking the number of calls you receive from prospects that are coming from all your social media platforms. This way, you can adjust your efforts however necessary to make sure your prospects can contact you whenever they need it.

These two key differences make it possible to understand exactly why VoIP phone systems have become so popular among businesses. They are convenient, flexible, easy to use and they contribute to successful communication not only with clients but also with partners and team members.
