Cloud Telephony & VOIP System Installation FAQs

  • VoIP stands for Voice Over Internet Protocol. It allows people to make phone calls using devices connected to the Internet instead of traditional telephone lines.

  • VoIP telephony is the underlying technology that enables online phone calls.

    Hosted and cloud VoIP are basically the same. They both mean the VoIP services are provided by a third-party VoIP company, including the hardware, software, and servers.

  • Because VoIP is done through the internet, it is exposed to security concerns that traditional telephone lines are safe from like hacking, malware, and distributed denial-of-service (DDoS) attacks.

    However, the growing reliance of businesses on VoIP has also increased the efforts of VoIP providers to secure their services from cyberattacks. Data encryption, firewalls, virtual private networks (VPNs), optimal router configurations, and solid IT security policies can ensure the safe use of VoIP systems.

  • VoIP providers make it easy to use the technology with intuitive software and reliable customer support. Just about every business these days is dependent on the Internet to conduct daily operations, too, so setting up VoIP is simple with a good Internet connection.

    In fact, VoIP increases work flexibility, as online phone calls can be done through devices other than a VoIP phone, including desktop computers, laptops, and smartphones.

  • VoIP companies provide and maintain their services virtually to clients if it’s hosted VoIP. Apart from the physical VoIP phones installed in the clients’ workplace, everything else is hosted and managed in the provider’s own location.

    With on-premise VoIP, your company is responsible for installing and maintaining the hardware and software in your place of business.

  • There are multiple factors to consider when estimating the cost of a business phone system, including:

    • How many people will be using it
    • How your office space will accommodate the necessary equipment
    • How many different sites your business has
    • What model you plan on using (VoIP or traditional)
    • What features you need (conferencing, call transfers, instant messaging, systems integration, etc.)
    • Employee training
    • Maintenance
    • Ongoing charges

    Because of the various aspects you need to account for that all affect each other, you have to compare the offerings of different providers.

  • As long as those people at home or other locations have internet access and a device with VoIP capabilities, you can connect to them with your VoIP phone at the office.

    Connecting to a landline phone while using a VoIP device is also possible by using a VoIP phone adapter with the landline phone.

  • Yes, you can use VoIP with cordless phones, mobiles, and laptops. Most modern devices can connect online, do calls over the Internet, and are compatible with VoIP software. There are also dedicated cordless phones that can do both VoIP and landline telephony.

  • Start-ups and SMEs can enjoy lower costs for over-the-phone business correspondence compared to using traditional landline systems.

    Your business can do more with increased functionality built-in to VoIP devices, from receiving faxes and voice mails to teleconferencing to remote access wherever there is internet available.

    If you are planning on growing your company, VoIP allows for rapid scaling with little reliance on additional software and hardware.

  • Yes, your VoIP phone numbers are virtual and not location-dependent. You can make and receive calls in a new office with the same VoIP number as long as you have access to the Internet.

  • The initial setup for VoIP is cheaper because all you need is a decent Internet connection. A single VoIP provider can take care of your office and mobile data needs. You typically only have to pay monthly instead of per call. Long-distance charges are non-existent. With hosted VoIP, the provider shoulders all the maintenance.

  • VoIP enables 24/7 global customer support. A customer can call a local number and be forwarded to external agencies, home workers, or your own customer service department no matter the time and day.

    VoIP functionalities include call monitoring and customer service software integration for more insight into the specific problems a customer might have.

    • VOIP phone sets for making and receiving calls
    • Analog telephone adapters if you want to connect a traditional landline phone to a VoIP network
    • Headsets if you want to do VoIP calls through your desktop or laptop computer
