SIP Trunking is a method by which business phone systems can operate using an internet connection instead of a traditional phone line.

SIP Trunking:
 

• Costs less – Saves money on your business phone bills

• Scales easier – Makes it easy to scale your operation pain-free

• Is more reliable – Offers increased phone service reliability
   

SIP trunking is provided by SIP providers, which are similar to traditional phone companies, except SIP providers give access to phone lines over the internet (and SIP service is significantly less expensive – sometimes as much as 60-80% less).
