Avaya phone compatibility with Cisco Unified Communications Platform

MrKristoff

Hello,

We are currently an all-Cisco user on the network routing, switching, and security side, however, we are an all-Avaya user on the phone, IP phone, and voice communications side.  I am fed-up with all the problems we have had with Avaya and would love to migrate to Cisco.  My department head wants to know is it possible to have a Cisco platform managing all the unified communications and voice mail on the back end, but continue to utilize Avaya phones currently in place in every office until such time as we can replace in the coming years through attrition?  This is primarily a cost measure which is the primary factor in management not wanting to make any changes whatsoever due to the investment made already in the existing system.

None of the Avaya endpoints are officially supported on Cisco CUCM, however if they are SIP phones they can be defined as 3rd party SIP endpoints.  With that being said you get by far most features and satisfaction with Cisco phones on CUCM, otherwise you are asking for another set of issues, and at that point one vendor will just point to another.

Hi

Please refer this document for more information on list of supported end points with Cisco unified communications platform and the compatibility matrix.  Only Cisco endpoints and sip phones are supported.

Hello Chris,

Thanks for the response.  Yes, I agree that a multi-vendor scenario often results in a blame-game when issues arise and that a full Cisco phone environment would be the most logical, beneficial, and least problematic deployment, however, being a government organization and given how much $ has been invested already in the current Avaya system, we are somewhat limited in our options for funding and such, and have been unsuccessful in getting funding approval for a complete phone system overhaul, so we have to do it piecemeal until we get to a point where more than 50% of our infrastructure is Cisco vs. Avaya, at which time we can then move for a full migration of the remaining hardware.  Definitely not the best solution, but seems to be our only option for getting where we ultimately want to be.
