Brief overview: what are VoIP and SIP?

As a business looking for effective communication systems, you've probably heard of VoIP and SIP. But you may be thinking, what are these two communication systems, and how could they benefit my business communications? 

What is VoIP?

VoIP stands for Voice over Internet Protocol. VoIP is a term for a call that's made over the internet rather than using a fixed-line communication system. 

What is SIP?

SIP stands for Session Initiation Protocol. SIP is a signalling protocol that enables the Voice Over Internet Protocol. SIP supports the signalling and management of voice, video, and electronic messaging applications. Simply put - it is used to manage multimedia system communication sessions in VoIP applications. 

What are SIP Trunks?

Businesses with an onsite VoIP phone system will usually also have something called "SIP Trunks", which run over your internet connection.

Session Initiation Protocol is just one of the possible protocols you can use for VoIP communications. SIP provides a way to convert voice signals into data that devices used by a caller can decode. 'Trunking' refers to an interconnection between phone lines and a shared communications network. SIP trunking allows us to partition the network into public and private domains. It securely delivers communication services to users equipped with private branch exchange.

The more concurrent phone calls you want, the more SIP trunks you'll need. When a business opts for a cloud-hosted phone system, they don't need to think about SIP, as that's all the provider's responsibility. Only if you have an onsite phone system or host your VoIP phone system in your company's private cloud will you need Session Initiation Protocol trunk channels.
