Save on your phone bills


SIP trunking is a way to enjoy significant savings on your current phone bill.

Sip Trunking or what should better be called a "VoIP Phone Line" is one of the best ways to leverage VoIP technology for a savings on phone bills.


There are a number of VoIP phone line providers in New Zealand to choose from.

What are the benefits of using SIP trunking?


Connections can be established by computers using a soft-client, IP phones, VoIP ready PBX systems and legacy phones systems by using a VoIP adapter.
The most common usage for SIP is VoIP - Voice over IP. In this case, telephone calls are not placed using the conventional telephone network (PSTN), but are routed over the Internet protocol TCP/IP. 


It’s been proven that businesses that utilize SIP Trunking save up to 70% more in expenses than businesses that have contracts with traditional phone companies. At IT Net World we can offer competitive pricing by the trunk or with bundled packages from different providers.

How SIP Trunking works


SIP trunking takes data, voice and video out over your Internet connection.  In the case of a phone call, the call either originates as an IP call or is converted to one before it leaves the office. 

This is done by the IP-PBX or a gateway device, like an ATA connected to an analog port on the PBX or a router with SIP capabilities.
