What is the Difference Between a SIP Trunk and a SIP Line?

SIP LineIf you want to update your Business Phone System without harming your budget, there are a few different options. One of the best ones is SIP Trunking. SIP is a way to modernize your phone system; rather than using copper wires to make calls, you use the internet. This benefits your company in numerous ways. For one, copper lines can only send voice data. The internet can handle not only voice but also multimedia signals. This makes instant messaging and video conferencing possible too. The best thing is that SIP Trunking also saves you money, especially for when you want to scale your telecommunications as you grow. However, with all new technology there comes a learning curve. If you don’t know a lot about the technology going into it, you might need some help understanding the terms phone providers use. For one, what is a SIP Trunk and a SIP Line? What is the difference between the two?

SIP Trunk

A SIP Trunk is what connects your PBX to the internet. It serves as the digital version of a traditional phone line. A SIP Trunk can have many SIP Lines attached to it. For example, a single SIP Trunk has the capability to support numerous desk phones, mobile phones, and softphones.

SIP Line

A SIP Line, as touched on above, stems from a SIP Trunk. It is also referred to as a session or a channel. SIP Lines are the lanes in which you send communication data back and forth between two points. They can support a single incoming or outgoing call. You can have numerous lines on one SIP Trunk. To determine how many lines you need, you simply need to figure out how many concurrent calls your company makes at any one time throughout the day.
