1. A method of routing an incoming call, comprising: receiving an incoming call at a call center of a language interpretation provider, wherein the incoming call is made by a customer requesting language interpretation service; determining a level of skill required by the customer, wherein the level of skill required represents a minimum skill set that an interpreter of the language interpretation provider should possess in order to provide the language interpretation service requested by the customer, wherein the language interpretation service is provided during the incoming call; queuing the incoming call at a first queue that distributes incoming calls to a call center interpreter, wherein the call center interpreter is permanently connected to the call center of the language interpretation provider through a voice link; and if a customer-defined event occurs, routing the incoming call to a second queue that distributes incoming calls to a non-call center interpreter, wherein the non-call center interpreter is not permanently connected to the call center of the language interpretation provider.
