Frequently Asked Questions

What is Sussex Mobi-Fi™?
Sussex Mobi-Fi™ is the ability to receive or make telephone calls from any device that can connect to the internet via a local area network, WiFi or 4G/5G wireless, such as a smart phone, tablet, laptop, or personal computer.
Does Sussex offer 911 service?

Yes, at no additional charge. However, the E911 service in the VoIP world is slightly different than that provided on a hard-wired Telco line; because there is no permanent location on the internet (an IP can be anywhere), the E911 operator will ask for a location, as opposed to being able to see it automatically. Your billing address (location of most businesses), is registered with the E911 call centre, as an assist to locating where the 911 call originated.

    • Do I have to be an existing Sussex customer to have a Mobi-Fi™ account?
  • No, your Mobi-Fi™ account is stand alone, and is available to those who wish to subscribe.
  • Remember, it costs nothing to have a Basic Mobi-Fi™ account; you only pay when you actually use it.
    • How does Sussex Mobi-Fi™ work?
  • By using a softphone application loaded on to your mobile device or pc, your device accesses the internet, and allows you to make telephone calls.
  • Mobi-Fi™ allows you to dial calls to a regular telephone or another Sussex Mobi-Fi™ account, located anywhere in the world.
    • What is the difference between the Basic and Enhanced service?
  • The Basic service provides outbound calling only.
  • The Enhanced service provides inbound and outbound calling, and comes with a telephone number, and voicemail.
    • What devices can use the Sussex Mobi-Fi™ capability?
  • Virtually any smart device that has internet connectivity via Wi-Fi, 3G/4G, or local area network.
  • These include most smart phones such as the Blackberry, IPhone or any Android phones; tablets, such as the iPad and any Windows tablets; many other devices such as notebooks.
  • You can also use your PC, if connected to the network, but this obviously limits the portability of the service.
    • Does Mobi-Fi™ handle voice, video and messaging?
  • Yes, for direct Mobi-Fi&trade to Mobi-Fi&trade, but it depends on the softphone.
  • Some softphones offer different capabilities on different devices, so look around for one that suits your needs.
    • What is a softphone?
  • Search the Internet. Many different free-ware softphones are available for download from your Apps Store.
  • We particularly recommend (all equal)
    • 3CX Phone, from www.3cx.com (for iPhone, iPad, Android o/s, Windows o/s) (voice, video, IM, depending on device)
    • Linphone (for Android o/s) (voice, video, IM)
    • Media5 Fone (for PC, iPhone, iPad, Android)
    • ExpressTalk from www.nch.com (for PC or notebook)(voice, video)
    • Zoiper (for the MAC)
  • Log on to these sites and follow the instructions for downloading their softphone or,
  • Depending on your device, go to your Apps store and search by name, or by the key words "VoIP phone", "sip phone", or "softphone".
  • There are several softphones available that are not free. Note that many so-called "free" softphones are tied to a particular VoIP carrier. The open free versions are sufficient for our service. Unfortunately, there appear to be very few free open BlackBerry softphone apps.
    • Does Sussex have its own proprietary softphone?
    Under development – coming soon!
    How easy is it to set up the softphone with the parameters for my Sussex Mobi-Fi™ account?
    There are basically three parameters that need to be entered into the softphone:
    • The username or SIP ID,
    • A password,
    • And the IP address of the Sussex server.
    These parameters are supplied to you by Sussex when you register for the account. We supply a basic setup "cheat-sheet" and we would be glad to assist in setup should you have a problem.
    What effect do firewalls have on the service?
  • Most public domain wi-fi hot spots are open and you should not incur any firewall blocking issues.
  • If a firewall is present, and is restricting your ability to make calls, it may be necessary to forward specific ports through the firewall to the internal IP address of your device.
    • Can I use my smartphone for just the Sussex Mobi-Fi™ service and by-pass voice calling using my cellular carrier?
  • Yes.
  • If you wish to by-pass your cellular carrier voice service and use your smartphone as purely a wi-fi or 3G/4G calling device, you will still need a data plan from either a cellular carrier or a wireless ISP. Note that most cellular carriers force you to pay for a combined voice and data plan on a smartphone, although not on a tablet or note book.
  • The Enhanced Sussex Mobi-Fi™ account gives you almost the same capability as a cellular phone, with the exception that calls can only be made and received when you are connected to the Internet, either via wi-fi or 4G/5G.
  • In many cases we can port your existing cellular number to your Mobi-Fi™ account.
    • Do I even need a cellular data plan, to use my Sussex Mobi-Fi™ account?
  • No, as long as your device is Wi-Fi compatible and you only use open Wi-Fi hotspots, or if you have a wireless internet service provider connection.
  • The cost savings can be very significant.
    • If I do have a cellular data plan, will Sussex Mobi-Fi™ use data bytes on my data plan?
  • Only if you allow connection to the internet via your data plan, and you are not in a Wi-Fi hotspot
  • The amount of data used for VoIP traffic is relatively minor.
