A telecommunications switch comprising a processor, memory accessible by the processor, and computer program instructions stored in the memory and executable by the processor to perform:

• receiving, at the telecommunications switch, a request to initiate a call from an originating party;
• selecting, at the telecommunications switch, from a list of terminating carrier networks, an evaluation service based on routing;
• wherein the evaluation service is included in the list of terminating carrier with highest priority and a terminating carrier with which the call is completed is included in the list of terminating carrier as a lower priority;
• routing, at the telecommunications switch, the request to initiate the call to the evaluation service;
• forwarding, from the evaluation service, a media prompt requesting the originating party to enter a response to the media prompt;
• and when the originating party does not enter a correct response to the media prompt, forwarding, from the evaluation service, an indication that the call is forbidden, and blocking the call, at the telecommunications switch, based on the incorrect response to the media prompt.

A computer program product comprising a non-transitory computer readable storage having program instructions embodied therewith, the program instructions executable by a computer, to cause the computer to perform a method comprising:

• receiving, at a telecommunications switch, a request to initiate a call from an originating party;
• selecting, at the telecommunications switch, from a list of terminating carrier networks, an evaluation service based on priority;
• wherein the evaluation service is included in the list of terminating carrier with highest priority and a terminating carrier with which the call is completed is included in the list of terminating carrier as a lower priority;
• routing, at the telecommunications switch, the request to initiate the call to the evaluation service;
• forwarding, from the evaluation service, a media prompt requesting the originating party to enter a response to the media prompt;
• and when the originating party does not enter a correct response to the media prompt, forwarding, from the evaluation service, an indication that the call is forbidden, and blocking the call, at the telecommunications switch, based on the incorrect response to the media prompt.

A method, implemented in a computer system comprising a processor, memory accessible by the processor, and computer program instructions stored in the memory and executable by the processor, the method comprising:

• receiving, at a telecommunications switch, a request to initiate a call from an originating party;
• selecting, at the telecommunications switch, from a list of terminating carrier networks, an evaluation service based on priority;
• wherein the evaluation service is included in the list of terminating carrier with highest priority and a terminating carrier with which the call is completed is included in the list of terminating carrier as a lower priority;
• routing, at the telecommunications switch, the request to initiate the call to the evaluation service;
• analyzing, at the evaluation service, a media dialog from the originating party to determine whether to allow the call;
• and when the evaluation service determines not to allow the call, forwarding, from the evaluation service, an indication that the call is forbidden, and blocking the call, at the telecommunications switch, based on the incorrect response to the media prompt.
