The benefits of a SIP Trunk mainly relate to reduce your costs, that can reduce to half of your current call price. Also, you pay per call not per channel and bundle voice channels such as ISDN or ISDN-2-30.

Besides the cost flexibility is a big advantage. The capacity, or bandwidth, can be rapidly increased or decreased.

The type of phone (analog, digital or IP) is not important. Another advantage is that there is no need for additional hardware, such as an ISDN card.

This also gives you a big cost saving.
