Reduce Your Telco Costs by Up to 50%


Cheap Calls

Enterprise Grade

Flexible Terms

SIP Trunks use Session Initiation Protocol (SIP) to deliver business grade telephone services over the internet. The technology, also known as Business VoIP, allows you to make and receive calls over a broadband internet connection.

Enterprise Grade SIP Trunks

In common terms, SIP Trunks are essentially business VoIP phone lines that can have one or multiple channels. The channels determine the number of concurrent phone calls that can be made. Multiple indial numbers with specific area code prefixes can be allocated to a SIP Trunk. These are fully portable and not restricted to a particular phone exchange area. Existing PSTN and ISDN landline numbers can also be migrated to a Business VoIP service.

Business VoIP and SIP Trunks are gradually replacing traditional telephone lines like PSTN and ISDN. With the rollout of the NBN and other broadband infrastructure, Australian businesses can now take advantage of this powerful and very flexible technology. SIP Trunks offer a much greater level of functionality and flexibility than traditional phone lines, and are ideal for businesses of all sizes. Businesses can reduce their fixed line telco costs by as much as 50% using SIP Trunks.

Difference Between Business Grade and Standard VoIP

Standard VoIP is a common technology that's only able to send voice messages and is usually deployed via an application. Business VoIP uses SIP (Session Initiation Protocol) which is a specific protocol designed to send voice, data and video messages.

SIP is a powerful protocol that can be deployed in more ways than standard VoIP. It has much greater functionality including video conferencing, delivers higher quality calls and is ideal for UC (unified communication) solutions.

Common Deployment of SIP Trunks

SIP Trunks can be deployed in a number of ways. They can either be connected to an existing PBX system and act as a replacement for traditional telephone lines; or programmed into an IP Phone and used as a stand alone telephone line with its own telephone number. They can also be programmed into a Soft Phone on either a laptop or a PC, or into a mobile phone. This is especially useful when traveling overseas as the call being made back to Australia is charged at local Australian rates.

  • Replace Your Existing PBX Phone Lines with SIP Trunks - majority of PBX phone systems installed in recent years are IP compatible and can be configured to use SIP trunks instead of traditional phone lines.

  • IP-PBX Systems - require SIP trunks to connect with the Public Switched Telephone Network (PSTN). 

  • IP Phones - a perfect solution as a replacement for stand alone telephone. Use with an IP video phone for conferencing.

  • PC or Laptop Softphone - use a headset to eliminate the need for a desk phone. Also suitable for UC applications including video conferencing.

  • Program Into a Mobile Phone App - use an app such as Bria to turn your mobile into a SIP phone. Ideal for international travelers who want to use their mobile to call Australia. Calls are charged at local call rates.
