This is straight out of my "Switching to VoIP" book (sorry if there will be mistakes in the writing...im gonna type & post...Im not an editor :-) Centrex Centrex is POTS enhanced with business-grade telephony features like call conferencing, four-digit dialing, and per-call billing rather than per-minute billing. It was designed to curb the need for small businesses to invest in PBX equipment in order to get modern telephony features. A single Centrex customer ca use many Centrex lines, collectively called a Centrex group. Within the group, each line can be called using four-digit dialing instead of the usual 7-digit dialing (i.e., the caller can omit the prefix when placing calls within her Centrex group). Some other PBX-like features include the ability to easily transfer calls between lines in the same group, or enable and disable call forwarding for a given line by dialing a special sequence of DTMF digits. Normally, users of Centrex have to dial an 8 or 9 at the beginning of each call that is destined for a receiver outside their Centrext group. Dont know if this exactly answers your question...but it seems you still need to pay for each line/extension in a Centrext group. Its just a way to get PBX-like features without having to buy a PBX. So if your customer is only buying two Centrext lines, they will only have two lines therefore two extensions.
