CUCM 14 Deprecated Phones

Planning an upgrade for your Cisco Unified Communications environment? Preparing technology budgets for next year? Look out for CUCM 14 deprecated phones.

Cisco had a surprise in store for long-time customers of their UC platform. They announced that a large selection of IP phone models would be deprecated with CUCM release 14.0.



  • Before making budget decisions, have a look at the list of CUCM 14 deprecated phones listed below.
  • Although Cisco backtracked on its decision to deprecate all the IP phones on the original list, the writing may be on the wall for those phones too.
  • That said, Cisco does not plan to support any End of Life (EOL) phones.
  • Cisco deprecates phones due to security issues, new features, and sustainability standards.
  • There are cloud and on-premises options to help you migrate deprecated phones to current models.


The silver lining: Cisco ultimately reversed its decision. According to Cisco, this “allowed their customers to get additional usage from working models of Cisco IP Phones and delayed a forced migration to alternate clients or phones during challenging business timeframes.” Their customers could move to newer phone models and clients at a reasonable pace.

The initial announcement of CUCM 14 deprecated phones showed which models were on the chopping block. It’s possible these phones will be deprecated when CUCM 15 is released. Check out our round-up of what those were, as well as which previous deprecations will carry over so that you’ll be prepared.


CUCM 14 deprecated phones

While Cisco ultimately decided not to deprecate any additional endpoints in Release 14, their policy to end of life phones hasn’t changed:

“Cisco will not issue bug fixes or security enhancements for endpoints that have reached End of Software Maintenance or End of Support status, regardless of whether those endpoints are deprecated or not deprecated. Cisco will not test Unified Communications Manager with End of Life phones. Nor will we fix Unified Communications Manager bugs that are related to End of Life phones unless the issue can be replicated on a phone that is not End of Life.”

Why does Cisco deprecate IP phones?

According to Cisco, there are several reasons why some phone models end up in the legacy bin:

  • Security: Legacy phone models are not updated with critical software fixes. Cisco’s ability to protect customers from security issues is limited.
  • New feature implementation: Some phone models were introduced more than ten years ago (e.g, 7900 series). Their old hardware makes implementing new features and new security features difficult or even impossible.
  • Sustainability: Cisco isn’t providing any development support or doing any regression testing for these older phones.


What can you do?

  • Check your inventory of IP phones, including phones that are currently not in use.
  • Plan the migration to other phone series like the 7800 and 8800 before moving to CUCM 14.
  • Look at alternative options, like migrating to cloud technology. ZIRO Parlay Cloud UC, powered by Cisco BroadCloud, could be exactly what you need.
