How many channels are in a SIP trunk?

A SIP trunk is a protocol that allows the transmission of media (voice, video, or text) via data networks, including the public internet, between locations. It enables bundling multiple channels/lines on one SIP connection, allowing businesses to virtualize these lines by dividing their 1GBPS connection by x number of times. A channel is a path between two points on a telephony system and represents the capacity for making calls from one place. The number of channels in a SIP trunk can be as many as needed, providing more control over call capacity while reducing costs and physical infrastructure requirements. As ISDN copper wire infrastructure is being replaced with public internet and cloud-based infrastructure globally, SIP trunks are becoming the industry standard for telecommunications.
