V1 VoIP explains what SIP trunking is, what it does, features and benefits and how to resell or wholesale the services and solutionsSIP trunking is one of the most popularly requested product from V1 VoIP for both resellers and wholesale agents. If you’ve wanted to add SIP trunking to your portfolio of services offered, allow us to explain exactly what it is, what it does and how to sell it!

SIP trunking stands for Session Initiation Protocol trunking. SIP is a service that allows an existing PBX or phone system to be connected to the Internet in order to use VoIP. A SIP trunk replaces your PSTN phone line with a VoIP equivalent. SIP is an IETF VoIP protocol that supports voice, text, video, and other online multimedia services.

Bandwidth is crucial when it comes to SIP trunking. You may need to purchase additional bandwidth for your SIP trunk and Internet use to work well without impacting one another.

Setting up a SIP trunking system requires a little bit of equipment, setup, and knowhow. You need three specific parts in order to have a properly functioning SIP trunking system. They are:
1. IP PBX
2. ITSP
3. Enterprise Border Element

First, make sure your existing PBX or phone system must be compatible with SIP trunking. You may need to upgrade your PBX software in order to use a SIP trunk, as older systems may not be compatible. A PBX that can work with a SIP trunk is frequently known as an IP PBX.

You will need an enterprise border element to SIP trunk. This connects your PBX or phone system to the internet and handles the traffic of the SIP trunking service. An enterprise border element is usually provided by the SIP trunking ITSP as it represents a significant investment. ITSP refers to the Internet telephony service provider and they will provide you with a SIP trunk.
