A SIP trunk is a virtual connection between a PBX and a VoIP provider. It allows businesses to make and receive phone calls over the internet, without the need for traditional phone lines. SIP trunks are an increasingly popular option for businesses of all sizes, as they offer a number of advantages over traditional phone lines, including cost savings, flexibility, and scalability.
SIP trunks are more cost-effective than traditional phone lines because they eliminate the need for expensive copper wiring and maintenance. They are also more flexible, as they can be easily moved or scaled up or down to meet the changing needs of a business. SIP trunks are also more scalable than traditional phone lines, as they can be used to support a large number of simultaneous calls.
