VoIP related telephony can sometimes prove confusing for customers. Do all of these acronyms (VoIP, SIP, PBX, etc.) just mean the same thing? They don’t, but that doesn’t mean that they aren’t interrelated. Before we get to SIP Trunking and PBXs, let’s start with VoIP. VoIP (or Voice over IP) is a way to send your voice communications over IP (or Internet Protocol) networks, i.e. the Internet. Having a rudimentary understanding of VoIP is important if you want to know the difference between SIP and Hosted PBX.
A Hosted PBX (private branch exchange) provides PBX functionality without having to keep all of the equipment at your office. PBX functionality includes features such as automatic call distribution, voicemail, auto attendants, call transfer, etc.). Hosted PBXs work with VoIP technology to route calls to extensions and still allow your provider to maintain the equipment.
SIP Trunking uses Internet Protocol to connect your phone calls to the PSTN (Public Switched Telephone Network). By using SIP, you replace traditional PRIs and analog lines. If you have an on-premise PBX, SIP is a great option because you can connect your PBX to your service provider by using a gateway. SIP Trunking works great for businesses because it combines your data and voice networks into a single network. By doing this, you end up saving as much as 50% off of your phone bill. SIP also allows you to only purchase trunks as you require, rather than in blocks.
Deciding Which Works Best For Your Business
Trying to decide between SIP Trunking and Hosted PBX can prove difficult for some customers. When doing so, it is important to consider which aspects and features are most beneficial to your unique business. If you need help, a qualified telecommunications provider should be able to make a suitable recommendation.
