ABSTRACT:
A method and apparatus for enabling dynamic codec selection on a per application basis are disclosed. Specifically, before establishing call legs to connect VoIP endpoints, the Call Control Element (CCE) consults any invoked application server to determine the preferred codec method and communicates this preference to the appropriate Border Elements involved in the call. The preferred codec method is then negotiated between the corresponding calls legs while the call media path is being established.
