9. A routing system for providing a communications service via a network comprising: a switch; a first link coupled to the switch and operable to relay a signal between a calling communications device and the switch; a second link coupled to the switch and operable to relay the signal between a called communications device and the switch; a third link coupled to the switch and operable to relay the signal between an operator communications device and the switch; a processor coupled to the switch operable to receive the signal from the first link and read a number associated with the calling communications device from the signal, and to selectively activate the switch as a function of the signal to communicably couple the first link to the second link; and a line condition module in a memory of a computer; wherein the processor is operable to compare the number associated with the calling communications device to a number stored in the memory, and to selectively, based on the comparison, activate the line condition module to monitor the signal as the signal is relayed between the first link and the second link.
