  • How do you make calls over a VOIP connection?

    VOIP or "Voice over Internet Protocol" is basically a telephone connection over the Internet. The hardware is instilled within the phone and works like a standard phone, with the added benefits of long-distance around the world calling without having to pay extravagant phone surcharges.

  • Is the quality of voice calling the same as traditional phones?

    The voice quality of VoIP in comparison to traditional landlines is usually pretty similar, but because data is sent over an internet-based network, quality cant be 100% guaranteed like a landline call. At FrontierPC our sales staff can help your business navigate through these common issues with consultation in terms of proper bandwidth, equipment, and location of your hardware to fully optimize your VoIP call quality.

  • What sort of internet connection do i need?

    A reliable broadband internet network such as DSL or cable is essential for high quality VoIP connection. The average internet provider provides at least 512 kbps which is usually more than enough for VoIP communication. Depending on your business preferences in terms of mobility, Wi-Fi connections are sufficient, but a cabled connection is preferred for optimum performance.

  • Can I keep my original phone number?

    Yes, your business can keep your existing landline number and port it to a VoIP service as long as the number is registered either under your name or company name.

  • What is an ATA device?

    An analog telephone adapter (ATA) is the hardware used to connect standard analog telephones or similar devices to an internet-based network. The ATA is connected to a modular jack and provides traditional dial tones and other standard telephone features.
