Avaya SA PREF CMM R6 w/CM R6 EE

Keep core voice services available and compliant with a three-year software maintenance package for Communications Manager R6. This offering preserves CM R6 EE entitlements while delivering software updates, security patches, and access to Avaya support channels tied to MPN 222367. For infrastructure teams managing multi-site telephony, the plan reduces upgrade risk by ensuring vendor-sourced fixes and compatibility guidance. Engineers retain access to software downloads and entitlement verification, accelerating remediation for incidents that would otherwise require prolonged internal troubleshooting. The engagement is scope-focused—software maintenance and vendor support—so you can maintain predictable operational costs while delegating complex version and patch management to the vendor. Choose this package when you require multi-year assurance for existing Avaya CMM R6 estates and need a direct vendor path for updates and entitlements.
