A Hosted VoIP Provider is an efficient party that can save you a lot of time in the field of telephony. It is important to choose the right provider, one you can trust and can grow with your organization. Luckily, you don't have to search for a company right around the corner because Hosted VoIP Providers are working remotely, via the internet.

What is a Hosted VoIP provider?

First of all you must know that VoIP (Voice over Internet Protocol) is a voice connection via a data line. This is a digital technique. The provider will setup a telephone system not physically within your organization, but at a remote location. This can be an IPBX (Intranet Private Branch Exchange). The (VoIP) devices can make a connection with the communications server through the broadband internet. Basics of Internet Telephony A VoIP connection works via an Internet Protocol, in contrast to the traditional Public Switched Telephone Network (PSTN) line. The data is sent in small, digital packets via the internet and to the correct destination. In the most simple form you can use VoIP on a PC with a headset which is connected to a special modem. The PC is running a piece of software that can transform the voice to data and send it through the internet. You can use a VoIP phone, a smartphone and even an analog telephone for this.

Hosted VoIP Providers "VoIP" stands for "Voice over IP". In other words voice communications via the internet. The outgoing and incoming lines go through the internet to an external service provider that delivers the voice data to the right place. Hardware and software needs to be maintained. If you are running it your own, you're responsible for this maintenance, that costs extra manpower and money. Software and firmware needs to be updated and at a loss the system must automatically switch to a backup system. That is a system that is present only in the event that the primary system should fall. In a Hosted Voice Service Provider environment this all is already centrally arranged, except for some maintenance of some facilities at the workplace. And even that can often be serviced by software and remotely. The investment costs of a private VoIP network are significant and you are still dependent on an ISP (Internet Service Provider) for the data to be send. The maintenance costs can also be damaged as well as license fee for the software. A Hosted Voice Provider saves a large part of the start-up costs and maintenance is often included in the price. One of the best Hosted Voip Provider in The Netherlands is Babbl Telecom BV. You can find them here
