SIP trunking, put simply, is a means of operating phone systems over the internet, instead of using a traditional phone line.
SIP stands for session initiation protocol.
Typically one SIP trunk is all your business needs to run all of your communications. Once your trunk is set up, you can scale up or down concurrent call capacity by adding or removing usage channels.
SIP trunking is cheaper than traditional business phone systems. We offer very competitive pricing with volume discounts as you scale. Find out more by talking to an expert to get a custom quote.
