Claim:
A method comprising: (a) receiving at a telecommunications terminal a series of inputs, each input corresponding to a data entry by a user of the telecommunications terminal; (b) determining, in response to at least one input having been received in the series of inputs, whether the user is placing a first call to a first private branch exchange, the determination being based on one or more of the inputs already received, wherein the telephone number M of the telecommunications terminal (i) is not in the address space of the first private branch exchange, and (ii) is mapped to a telephone number N in the address space of the first private branch exchange; (c) placing, in response to determining that the user is placing the first call to the first private branch exchange, a second call from the telecommunications terminal to a second private branch exchange whose address space does not contain M and does not contain a telephone number to which M is mapped; and (d) receiving at least one additional input from the user of the telecommunications terminal, wherein the at least one additional input would have been necessary to complete the first call.
