  1. What is a kiwivoip 028 number?
    A. A kiwivoip 028 number functions like a mobile phone number. It costs the same rate to call it no matter where you are in New Zealand. However, calling an 028 number from another kiwivoip phone will be free of charge – since all kiwivoip plans allow ‘Unlimited kiwivoip calling’. The cost of calling an 028 number from a non-kiwivoip phone will depend on your telephone operator – but the rate should be equivalent to another NZ mobile (or count towards your minute bundle if calling in from a mobile phone)
  2.  Can I bring my current phone number to kiwivoip?
    A. Yes. Please see our Porting Guide for more information
  3.  What is a kiwivoip local number?
    A. A kiwivoip local number is tied to a local region within New Zealand. Callers within that local region can call your number for free.
  4.  Do I get a voicemail box with every kiwivoip phone line?
    A. Yes – every kiwivoip phone line has its own voicemail box
  5.  Does every kiwivoip line have its own set of features?
    A. Yes – each kiwivoip phone and fax line has a separately configurable set of phone or fax features.

    A. This is dependent on the plan you choose.
  7.  Can I make calls to 0900 numbers?
    A. No, calls to 0900 numbers are not currently available
  8.  Can I make 111 calls on kiwivoip?
    A. kiwivoip do not support emergency calling. However if you do make a 111 call it will connect if possible. The operator will not know your physical location so you will need to provide this information to them.

    Q. How many simultaneous calls can I make through kiwivoip?
  9. This depends on which plan you are signed up on. The personal plans page lists the amount of concurrent calls that are available on the personal plans. If more than one person will be making calls at the same time on your kiwivoip account then you should consider the Business Plans the number of concurrent calls available on these plans can be seen on the business plans page. If you add additional local (non-028) numbers onto your account then you will get 1 additional concurrent call for each additional number that you add to your account. If you require more simultaneous calls on your account then contact and you can purchase additional simultaneous call blocks of 5 to increase the number of calls that can be made on your account.
  10.  How much data will my calls use?
    A. This will depend on the codec you use for your calls. We’ve put together some examples using the most commonly used kiwivoip codecs to give you an idea. One thing you need to keep in mind is that calls use data is both directions so you will need to consider both download and upload usage.

With a G.729 call you should allow at least 240 KB (kilobytes) in each direction per minute of call, or 28.8 MB (Megabytes) per hour in total. This translates to around 170 hours of calls on a 5 GB (Gigabyte) data plan.

With a G.711 call you should allow around 660 KB (kilobytes) in each direction per minute of call, or 79.2 MB (Megabytes) per hour in total. This translates to 63 hours of calls on a 5 GB (Gigabyte) data plan.

Please note that figures are estimates of the data requirements used for a call using a specified code. Actual requirements can change based on phone usage patterns and your connection type to the internet. DSL plans for example may include additional overheads and usage applied by your service provider. These calculations should only be used as a guide and we take no responsibility for the amount of actual bandwidth used.
