Isn't all VoIP the same?

No, there are a number of differences that will affect the quality of the calls so you need to be careful selecting your VoIP operator. Things to look for include:

• Ensuring that your calls are carried over a dedicated VoIP network and not just the public Internet;
  
  
• That voice traffic is prioritised over standard data, with an industry standard of Quality of Service (QoS); and
  
  
• That your network is monitored and available 24/7.

These are the levels of service and quality that ISPhone has brought to the Australian VoIP market.
