VoIP performs best with a small amount dedicated bandwidth, a quality focused codec used and low latency from the handset to the SIP trunk provider.

While it is possible to use a IP based phone system when a few of these requirements are absent, you will have to keep in mind that the quality of the service will drop, sometimes quite drastically.

Satellite Tower

Can you use VoIP over satellite Internet?

Voice over IP (VoIP) will work over satellite internet, however not necessarily well or reliably, due to a number of quality factors impacted by Satellite connections. These include:

  • Latency
  • Jitter
  • Bandwidth
  • Packet loss

As seen below, latency in particular can become a real issue over satellite internet connections, causing a noticable delay in communication.

When is a satellite connection implemented?

A satellite internet connection is usually implemented as a last chance of getting a connection to the internet. These are generally places such as a rural home or businesses, or as a redundant internet link.

Whether it’s a rural home or rural business, using an IP based phone system may be the only choice for having a phone system at all. It is common that the legacy copper/mobile infrastructure won’t be available to the rural parts of Australia and New Zealand, therefore making it impossible to make or receive phone calls.

Latency over satellite

When using a Satellite Connection as your primary link, you will adjust to the latency also associated with it. Any requests you send, whether you’re browsing the internet or sending voice packets via VoIP, will have to be sent to the satellites above the Earth in space, and then to your desired destination. When thinking in terms of SIP trunking, your voice packets will have to make this trip before even making it to your SIP provider.

This latency causes your voice on the call to be delayed and makes it feel like you are talking to someone on the other side of the world, even if they are in the same country.

We have found that when speaking with customers and partners who have implemented a IP based phone system over Satellite that they are extremely happy with the service they are getting, but have mentioned that the person on the other end of the call does notice.
