When SIP Trunking was first introduced, no one thought it would become as prevalent as it currently is. Nowadays though, it is one of the most common solutions on the market. This is due to its’ many benefits (such as features and cost savings). However, not everyone appreciates the intricacies of SIP. Here is everything you need to know about it:
What is SIP Trunking?
First of all, what is SIP? SIP stands for Session Initiation Protocol. It describes the process by which phone calls take place through the internet as opposed to traditional phone lines. As long as you have a phone number, you can easily reach anyone in the world.
SIP works by using an existing PBX (Private Branch Exchange) to route outbound and inbound calls. To make SIP work you need to connect your PBX to the cloud. Doing so gives your business flexibility and benefits you won’t get with traditional systems.
SIP Trunking vs VoIP
Are SIP and VoIP the same thing? While they are similar (and they work together) they are not the same thing. VoIP (Voice over Internet Protocol) describes using the internet to make calls in general. It is one of the main alternatives to using costly PSTN lines.
SIP Trunking, on the other hand, is more specific. It is the act of using VoIP to connect traditional lines to cloud systems. SIP is beneficial for companies looking to bridge the gap between traditional lines and complete cloud systems. It is a great way to leverage your current infrastructure.
Benefits of SIP Trunking
As alluded to above, SIP Trunking has many benefits. It can lower your monthly phone bill and offer you more functionality. It also has important features not found in traditional systems. For example, SIP supports bursting. This means that you can manage peak call volumes. Furthermore, because you are calling over the internet, you can make unlimited local and long-distance calls.
