Reliable & Secure VOIP

Our Promise To You

To ensure the best experience, we enable Quality of Service on the network which prioritises latency-sensitive traffic such as VoIP. We never overload the network. As a result, your network usage doesn’t contend with others for bandwidth. This means better response and genuine fast internet speeds.

Some VoIP providers cut costs by taking advantage of cheap Australian calls originating from overseas networks. Australian calls are sent overseas and then back into Australia. This practice results in a degradation of voice quality and reliability. We have ISDN voice termination to multiple tiers 1 carriers in Australia and never send calls overseas (unless you are calling overseas).
