How to Pick the Right VoIP Provider for You

Your VoIP solution is one of, if not the most important parts of your call center operations. As such, it’s critical that you choose a solution that matches your business needs and wants. Aspects of VoIP operators you should consider include:

#1: Assess Your Business Needs & Goals

The first and biggest consideration in choosing a VoIP service provider is the type of call center system, as this affects costs, deployment, features, and nearly everything else. There are two main types to choose from.

Hosted VoIP refers to cloud-based systems completely managed by 3rd party VoIP operators. These come at a lower price but give you limited control compared to On-Premise VoIP, which works off of pre-existing location-based infrastructure.

#2: Consider Your Specific Use Case

Different providers specialize in solutions based on business size or specific use cases. For example, a solution focused on SMB customer support may be more affordable but offer fewer features and international numbers.

On the other hand, a provider primarily selling to outbound, enterprise-size call centers will be much more expensive but offer numerous features, integrations, international numbers, and high call quality.

H3: #3: Evaluate Capacity & Features

How many agents you onboard naturally influence the price of your solution. However, many providers have a minimum/maximum number of users on their pricing plans, which can cause issues when selecting the correct plan.

For example, if you have only a few agents but need high-tier features, you may need to buy add-ons or more licenses than you need. Similarly, if you have a lot of agents but low feature requirements, you still might get stuck with a more expensive plan.

H3: #4: Assess Number Selection

The amount, type, and geographical location of numbers a VoIP provider can offer greatly depends on their connections within the industry, including local providers, regulators, etc.

As such, it’s best practice to not only look at the numbers you want to port right away but also think into the future and consider your expansion plans(international numbers) or possible initiatives (toll-free numbers).
