摘要:
A technique for allocating resources in a call processing system is disclosed whereby different levels of resources are allocated depending upon the available headroom in the system. The technique allows advanced and better performing signal processing methods to be used when the system is relatively idle, and acceptable but less robust algorithms to be used when system loading is heavy.

摘要:
An MF digit or DTMF digit detector identifies MF digits or DTMF digits in a signal and eliminates talkoff as a source of false detection by analyzing the frequency spectrum of the signal which is provided by FFT and by using the history of the signal to determine whether an MF digit or a DTMF digit was simulated by a human voice.
