Questions about VoIP?

What is a VoIP phone?

VoIP phones use hardware and software to handle telephone calls using voice over internet protocol (VoIP) technology.

Phone calls are placed over internet connections rather than the traditional legacy technology of the Public Switched Telephone Network (PSTN) or Integrated Services Digital Network (ISDN). VoIP telephone systems draw their power over ethernet.

You’ll find that due to the reduced infrastructure needed to deliver cloud voice calls on VoIP technology, calls can be provided at a very low cost.

As VoIP also uses the internet to deliver your phone system, many new features and services are available to small and medium-sized businesses that were previously unaffordable, such as voicemail-to-email, call recording, music-on-hold and call divert.

What does VoIP stand for?

VoIP stands for Voice over Internet Protocol. This basically means that phone calls are transmitted through the internet network rather than the traditional copper-wire network built for the telephone system.

Can you use VoIP phones as a regular phone?

Yes. VoIP phones can do everything a regular landline or mobile phone can. At its simplest, you still get your usual desk phone handset. You can even use cordless phones.

This can be used to ring and dial out to make and receive calls. The only difference is that your voice is communicated via internet connections rather than copper lines.

Some services, such as our Bluecube Cloud Voice technology, can take advantage of this and can allow you to direct your landline calls to your mobile device. This means that you don’t have to be anywhere near your handset to make or receive landline calls.

Are VoIP phone systems suitable for small businesses?

Small businesses that think big need VoIP. Due to the extensive features lists at a reasonable cost, VoIP phone systems are the perfect option for small businesses. VoIP phone features allow small businesses to gain access to settings previously only reserved for large enterprises. For example; call recording, on-hold marketing and remote working options. Because VoIP systems are set up per user and through an existing internet connection, they are great for expanding businesses.

Does VoIP require internet connections?

Yes. VoIP requires an internet connection to make and receive phone calls. This is can be through a wired connection, a Wi-Fi connection or mobile data connection. Typically we suggest that businesses run their VoIP connection through a separate internet connection for the best service.

What is the price of a VoIP office phone system?

Different factors can vary pricing. The size of your team. Type of handset you want. Additional extras you might want to include to your package. All these can influence how much a system can cost. Typically, the value you get from the system far outweighs traditional phone lines.

What are the advantages of using VoIP?

Using a VoIP phone system has several advantages for businesses.

VoIP provides communication at a lower cost compared to traditional landline phones. It can also introduce many feature-rich advantages that previously required a large internal infrastructure.

This means even small businesses can now introduce features such as on-hold marketing, call recording, voicemail-to-email. CRM integration, remote working via device sync and much more can also be introduced.

VoIP phones also allow for easy scalability for growing businesses. Traditional landline phones required costly upgrades or extensions to a business phone system upon the intake of new employees. With VoIP system technology, a handset can very quickly and easily be introduced into the network via an existing ethernet port.

Are VoIP phone systems cheaper than a landline?

VoIP based technology is significantly cheaper than traditional phone lines. This is because it does not rely on the legacy technology of PSTN & ISDN to provide a connection. These traditional lines are copper-based networks that providers find expensive to maintain.

Additionally, using a cloud-based phone system also introduces many features and benefits for businesses of all size. This allows businesses to get better value-for-money from VoIP systems compared to traditional landlines.
