A SIP trunk is measured by the number of calls that are allowed to flow across the connection. This measurement is called ‘CHANNELS’. In order for your business to make two calls from the building, you would need a SIP Trunk with two channels likewise, if three calls need to be made then three channels would be required.

Channels can be used for either inbound calls or outbound calls. If a company has three calls in progress, and one is outbound, and two are inbound, they will need a SIP Trunk with a channel level of three.

How do SIP trunks work?

It’s simple, for a SIP trunk to work, your business needs an adequate internet connection (this is to ensure communication within your business is at utmost efficiency), phones and a pre-existing IP-PBX system. When calls are made in your business, their translated to data packets are then sent over your data network. The number of SIP trunks your business has will be solely determined by your company’s needs.
