What is Enterprise VoIP?
Enterprise VoIP is considered the best service for established companies. Companies can seamlessly scale services up or down as per their requirement. Connectivity is commendable and all the credit goes to the advanced routing and analytics features. You can get Enterprise VoIP with the help of a cloud service provider.
How to Select the Best Enterprise VoIP Service Provider?
VoIP Enterprise solution allows you to scale up or down as per your budget as well as need. You are allowed to come down if you require fewer VoIP features. Here is what to consider while choosing an enterprise VoIP solution:
Know Your Budget
For a new Enterprise VoIP (if you are switching from PBX VoIP), you have to purchase a new phone system, upgrade your routers and pay a little amount to keep your number. Well, this will be way affordable as compared to the cost of maintenance. It is important for you to know your enterprise needs and how much you can spend on the VoIP system.
Check the Bandwidth
Your bandwidth can be consumed by VoIP telephony. If you owner of an enterprise we are assuming you already have a plan with your ISP.
Ensure you have a QoS router especially when you plan to switch to Enterprise VoIP. As this router helps real-time data to cross over audio/video channels like mail. For establishing a high-quality VoIP solution, you require the best hardware in the right place.
A good service provider will discuss your bandwidth requirement as per the lines needed. Different providers also offer internet services. But in that case, the data travels via their network and not from a public network.
On-Premise vs. Hybrid vs. Cloud Hosted: How are they different?
Most of the Enterprise VoIP providers are either cloud-based or hosted. Cloud-based or hosted services own data center. Dedicated experts are always there to provide you best services.
Your VoIP service provider has servers. The enterprise VoIP can call different landlines similar to the traditional phone.
On-premise means that stays in your office. They can be set up on the entire floor or complete building as per requirements. But in this case, you have to buy new equipment.
Hybrid is a mix of both giving you the best features and is designed for your business.
What to Expect from a Reliable Enterprise VoIP Service Provider
A service provider should help you tell their USPs. By that we mean, what makes their services different from other competitors. Compare their features, plans, scalability options, reviews, and support options.
Enterprise VoIP Phone Systems: Advantages
Real-time Scaling
The major benefit of Enterprise VoIP is, that it can upscale or downscale as per your current needs. That is why you don’t have to overthink about paying extra for the service you are not using.
Managing Remote Team
Smartphone applications, as well as IP seamless, connect with Enterprise VoIP so that you get a user-friendly experience.
“Find Me” & “Follow Me” regardless of where you are, you will always stay connected.
Advanced Call Routing
Most enterprises don’t want to be interrupted. So for them, this is the best solution. Set your phone to “Don Not Disturb” and work uninterruptedly.
Besides this, a few calls can be set so that they are received by others or to voicemail.
Third-party Integration
VoIP allows you to integrate with the existing software like CRM services, collaboration software, mail, accounting, etc.
