Information about VoIP Providers

VoIP Providers - VoIP System Service

VoIP phone systems (Voice over Internet Protocol) are a fast growing form of Internet telephony, enabling businesses to place calls by using a broadband connection, instead of the Public Switched Telephone Network (PSTN). This particular business telephone system is a cost efficient and reliable option for businesses of all sizes, especially the multinational. The infrastructure of the VoIP phone system includes a strong Internet connection, an adapter, modem, hardware (phone sets), and a VoIP subscription.

There are many suppliers of business VoIP phones and a guided selection of the most suitable one is a crucial decision when shifting to VoIP services. Call quality and maintenance rely mainly on the VoIP, service provider, so before making a decision, there are a few important things to be considered. This is a costly investment, so business owners should carefully research provider options, so they can get value for their money at the end.

Important Factors for Choosing a VoIP Service Provider

  • Quality of calls

With Internet telephony, calls can easily be distorted, causing a bad audio connection, which is something that no business owner wants to happen with their customer service. Some inflictions in call quality can be background noise, echo, speech delay or straight out failing of the call.

As this is difficult to estimate without actually trying out the service, businesses can ask providers about their MOS score. In broad, nontechnical terms, MOS (Mean opinion score) is is a unit which measures the overall call quality. It ranges from 1 to 5, with 5 being the best possible quality.

  • Features

As VoIP phone systems generally have similar features, different providers often include a different range of functionalities, included in their plan. For instance, if you take the voicemail transcription service, one provider may support voicemail to email function, while the other may also include voicemail to text message. Those are small variations in functionalities, but businesses with special communication needs need to consider if what the supplier offers is sufficient enough for them.

  • Subscription price

VoIP providers operate on different prices, but that is often because different benefits are included. One provider may offer a plan for £20 a month and another one for £35, but the latter may have included more international minutes and features, which the first one will consider as add ons. Many people tend to be discouraged when they see a high price and resort to another supplier for a lower one, but with the customisation and addition of features, they may end up paying a much higher price.

  • Set up and customer portal

The best VoIP service providers should aim to provide their customer with a transparent experience, both regarding setup and navigation through customer portals. They may have a complicated interface, causing the customer to not be sure of where they can find relevant information or add features to their service. This may seem unimportant, but it is crucial for the overall service since business owners should have easy access to all features and easily check and adapt their service plan.

  • International and long-distance calls

The best VoIP services offer significant cost savings regarding international calls, but VoIP providers may emphasise on different things for their customers. Some providers can offer a large number of long distance and international call time, while others may seem like they have neglected it in their service. Usually, they will provide different rates for international telephony and minute plans, that should be carefully considered before making a choice. Businesses need to estimate their internal telephone system needs and pick a provider that is ready to correspond perfectly with them.

  • Maintenance and support

This is included in the subscription price, so service levels from VoIP providers should be on a high level. Businesses need to think about fast responsiveness, personal attention to the customer and quick problem-solving. In case something with the VoIP software goes wrong and the whole system shuts down it is crucial to have someone who is able to react quickly and give you proper service. Many providers offer not only a full day available phone support, but also live chats and other platforms where customers can easily contact them for emergencies.
