One of the many benefits of VoIP PBX is the free calling between extensions. But if you use your PBX as an office PBX, you will also need a connection to the PSTN network. This connection is known as an SIP Trunk, which stands for Session Initiation Protocol, which is used to set up the Voice over IP connection.

With an SIP trunk, you are able to call fixed, mobile and international phone number, allowing you to reach anyone in the world at any time. Here at VOIPcomplete, we offer our own quality Prepaid SIP trunking service, which can be optionally combined with a Direct Inward Dialing (DID) Number. To view our tariffs, click on the link below:

We support all common codecs, including the G.722 wideband codec for superior audio quality and clarity. When you sign up, we immediately send you a login and password combination as well as the SIP server that you will be using. Once you configure these to your PBX, SIP phone or other SIP-ready equipment, you will start saving on calling costs based on the following table:
