The term ‘VoIP’ refers to multiple services that all involve placing calls over the internet instead of the traditional copper wires of the Public Switched Telephone Network (PSTN). This means, to install VoIP services, you need to be connected to the internet. The two main services are Hosted PBX and SIP trunks, which can involve a variety of different features and functions depending on your service provider.
Hosted PBX (also known as virtual PBX, Cloud IP PBX and IP Centrex) is a telephone system that provides advanced calling features while eliminating the need for on-site equipment. The only equipment involved to set up and use a hosted PBX system is the purchase of IP phones. This is why VoIP telephony services are often referred to as “Plug and Play” (also, IP phones can typically be reused when changing VoIP providers).
In addition to traditional call features (such as Do not Disturb, Call Conferencing, Call Forward etc.), a hosted PBX offers advanced calling features. This includes an advanced call coverage feature called Find Me Follow Me (FMFM). FMFM lets you forward your calls to one or several phone numbers simultaneously to never miss a call. Another advanced calling feature is Voicemail-to-Email which automatically delivers voice messages to your email. There are also a number of different advanced functions that a hosted PBX can create using customized call routing. Some examples include:
A SIP Trunk (also known as IP trunking or SIP trunking) is a VoIP service that allows the user to maintain their existing telephone system and existing telephones. A SIP Trunk enables the user to connect to the PSTN over the internet rather than using traditional copper wires. Although this method usually results in great cost savings (due to line pooling, which is the ability to share phone lines across multiple physical locations), the calling features and some functionality is restricted to the PBX that is already in use by the business.
With this comparison in mind, if you’re switching to a VoIP service and would like to know which one is best for your business, ask yourself the following questions:
