Patent ID: 7983410

Claim:
A method for prolonging feedback to a calling party that call setup is still proceeding, the method comprising: receiving, by a first data-processing system from a calling telecommunications terminal, a call to a first telecommunications terminal that is registered with the first data-processing system; directing, by the first data-processing system, the call to a second telecommunications terminal that is registered with a second data-processing system; refraining, by the first data-processing system, from transmitting a ringback signal to the calling telecommunications terminal, until a response is received by the first data-processing system from the second data-processing system, wherein response indicates that the second telecommunications terminal has been notified of the call; and transmitting, by the first data-processing system to the calling telecommunications terminal, a feedback signal while refraining from transmitting the ringback signal, wherein: i. the feedback signal is different from the ringback signal, and ii. the feedback signal indicates that call setup for the call is still proceeding; and iii. the feedback signal prolongs an indication to the calling party of the calling telecommunications terminal that call setup for the call to the first telecommunications terminal is still proceeding by causing the calling telecommunications terminal to output at least one of a clicking sound and a comfort noise.
