10. The apparatus of claim 1, wherein the plurality of internet protocol calls comprises an internet protocol call, wherein the one or more criteria comprise a list of one or more internet protocol call endpoints to monitor;

wherein the call control component receives a call setup request from a first internet protocol call endpoint to initiate the internet protocol call with a second internet protocol call endpoint;

wherein the call control component searches the list for an indication of one or more of the first internet protocol call endpoint and the second internet protocol call endpoint.

11. The apparatus of claim 10, wherein the call control component selects the internet protocol call from the plurality of internet protocol calls based on a presence in the list of the indication of the one or more of the first internet protocol call endpoint and the second internet protocol call endpoint;
