Abstract
A call processing system comprises first and second interfaces configured to selectively pass voice signals and data signals between caller and agent to enable communication. An attenuation means is configured to selectively attenuate voice and data signals passing from the first interface to the second interface to impede the agent from receiving voice and data signals from the caller. While a string of discrete data signals is received at the first interface, the system is configured to operate exclusively in each of: a first mode in which voice and data signals are permitted to pass from the first interface to the second interface to enable the agent to receive them from the caller; and a second mode in which the attenuation means attenuates voice and data signals passing from the first interface to the second interface to impede the agent from receiving them from the caller.
