Claim:
A method comprising: establishing, by a private branch exchange, a call between a first telecommunications terminal and a second telecommunications terminal; adding, by the private branch exchange, a third telecommunications terminal to the call while the call is in progress, wherein the private branch exchange: i. comprises an affiliation between the first telecommunications terminal and the third telecommunications terminal, and ii. adds the third telecommunications terminal to the call without transmitting any indication to the second telecommunications terminal that the third telecommunications terminal is being added to the call; and dropping, by the private branch exchange, the first telecommunications terminal from the call when the third telecommunications terminal goes off-hook; wherein the affiliation designates one of the first telecommunications terminal and the third telecommunications terminal to be a façade for both the first telecommunications terminal and the third telecommunications terminal, and wherein the private branch exchange is to represent either the first telecommunications terminal or the third telecommunications terminal using the telephone number of the façade, wherein the façade comprises an automatic number identification or caller-ID of one telecommunications terminal when the automatic number identification or caller-ID of the one telecommunications terminal is used by another telecommunications terminal.
