For your reference:
To recertify, pass ONE of the following before the certification expiration date:
- Pass any current 642-XXX Professional level exam, or
- Pass any current CCIE Written Exam, or
- Pass the current CCDE Written Exam OR current CCDE Practical Exam, or
- Pass the Cisco Certified Architect (CCAr) interview AND the CCAr board review to extend lower certifications.
To recertify the CCNP Voice Certification, you can take and pass one Professional level 642 exam by or before the certification expiration date. Any 642 prefix exam under a professional level certification track such as CCNP, CCDP, CCNP Wireless, etc. is considered a professional level exam.
However, the 642-165 UCCX exam will not qualify to recertify the CCNP Voice Certification because it is not a professional level exam.
For additional recertification options or information, you can reference the information provided by the user above or visit the CCNP Voice Recertification page.
