Hi Norm trees,
To recertify your CCNP Voice certification (formerly known as CCVP) you must pass a current professional level 642-XXX exam before your certification expires.
Unfortunately, passing the 642-583 SSSE exam will not satisfy the requirement to recertify a valid CCNP Voice certification because it is not a 642-XXX professional level exam.
Any 642 prefix exam under a professional level certification track such as CCDP, CCIP, CCNP Wireless, etc. is considered a professional level exam. Please note that not all 642 prefix exams are professional level because they may not be part of the professional level curriculum, such as the 642-583 SSSE exam.

Hope this helps.
