How many lines are in a PRI?

A PRI is technically one line, but it can simultaneously transmit 23 separate communications (voice, data, or video.) This means up to 23 people in your company can be on the phone (or sending an IM or having a video chat) at the same time. Each of a PRI’s channels has a 64 kbps capacity for data transmissions.
