1. A method of providing a relayed language interpretation service, comprising: receiving a language interpretation call from a caller at a language interpretation provider; determining a caller language corresponding to a language spoken of the caller; engaging a first interpreter that speaks the caller language and a base language; receiving an indication from the caller that the caller needs interpretation between the caller language and a third-party language; engaging a second interpreter to the language interpretation call that speaks the base language and the third-party language; engaging the third-party to the language interpretation call; and providing over-the-phone interpretation of the caller language into the base language by the first interpreter and over-the-phone interpretation of the base language into the third-party language by the second interpreter such that a conversation is established between the caller and the third-party, the second interpreter hearing the over-the-phone interpretation by the first interpreter so that the second interpreter utilizes the base language for the over-the-phone interpretation of the base language into the third-party language.
