SIP trunking

SIP trunking is a way for companies to save money on telephone calls. Instead of having a traditional team of phone lines, SIP trunking lets companies connect their phone systems to the internet, and then use the internet to make and receive calls. This way, companies don't have to pay for all of the phone lines they would need to make and receive calls - they can instead just pay for the internet connection they use to make and receive calls with SIP trunking.
