    Maintenance and Support for Avaya CM6.3 After EoMS

    The Avaya Product Lifecycle has moved on. As of July 9, 2018, the Avaya CM6.3 calling suite is End of Manufacturer Support (EoMS). As the name implies, parts and patches for this system are no longer being produced by the manufacturer. Therefore, support for the system is harder to find. Thankfully, there is a way for current users of the CM6.3 to receive the support they need.

    Extending the Life of Your CM6.3 System

    It may not be time to replace the CM6.3 just yet. For current CM6 users with strong systems, there are several options to keep your system running. Avaya will offer support of its own, but some users may be better off exploring a different option.

    Avaya Extended Support

    When an Avaya system reaches EoMS, Avaya Extended Support begins. With extended support, many of Avaya’s maintenance and support features are included, such a Tier III resource access and parts replacement. A natural extension of Avaya’s Product Lifecycle, Extended Support comes automatically after EoMS with no extra cost.

    Unfortunately, there are two major drawbacks to Extended Support. When it comes to services such as deploying parts, support is measured on a “best-effort” basis and done at Avaya’s own discretion. This becomes a problem when EoMS renders parts scarce.

    Furthermore, Extended Support isn’t permanent. After a certain amount of time, it will come to an end, and Remote Only support will take its place.


    The end goal of the Avaya Product Lifecycle is for users to upgrade their systems. While upgrades can be expensive and time-consuming, it’s worth going over what this option would entail.

    CM6 users may feel pressure to upgrade a system when it isn't necessary.

    Currently, the Avaya CM7 has also passed its EoMS date, making an upgrade to that system hardly any better than the CM6. Avaya’s newest system, the CM8.1.3, combines both cloud-based software and SIP connections to deliver the features of a classic PBX for a modern workplace.

    The CM8 is a promising system, but it comes at a high cost. If the system is still working for CM6 users, they may feel pressure to upgrade their system when it isn't necessary. These users would benefit most from the third and final option.

    TPM providers can support systems as old as the CM6.3, perhaps even older.

    Avaya Third-Party Maintenance

    Avaya systems don’t necessarily need Avaya support. Third-Party Maintenance (TPM) is also an option. TPM providers can support older systems such as CM6.3 since they don't follow the Avaya product lifecycle.

    TPM offers all the features of Avaya extended support from Tier III engineer access to parts replacement. It also offers all-around better service for a price lower than Avaya. TPM providers follow your timetable, not the OEMs. You’ll be able to get the same level of support regardless of where your system is on the product lifecycle.
