A Seat-Count Threshold, Not a Cloud Ideology, Is Now Deciding Who Runs Contact Centers
Avaya told customers in February 2025 that its Experience Platform (AXP) Public Cloud would enforce a 200-agent-seat monthly minimum from June 30, 2025, effectively forcing every contact center below that size to look elsewhere. Mitel, with more than 70 million users across over 100 countries, is facing similar customer unease over ownership changes and an unclear AI roadmap. RingCentral has held a migration partnership with Mitel since 2021, but that arrangement is no longer exclusive. Meanwhile Genesys says its Cloud platform passed $2.1 billion in annual recurring revenue and had risen to nearly $2.5 billion by early 2026, on 35% year-over-year cloud revenue growth — figures cited by CX Today on April 15, 2026, as vendors including NICE, Cisco, RingCentral, 8x8 and Five9 compete for the displaced customer base.
Does the 200-seat rule actually apply to my contact center?
If your Avaya AXP Public Cloud contract runs below 200 agents, yes — that floor became effective June 30, 2025, with no smaller tier offered.
Anyone above the threshold has more breathing room, but that doesn't mean stability. Avaya's response for larger customers is Infinity, a hybrid platform mixing on-premises and cloud workflows aimed at enterprises that want modernization without a full rip-and-replace. Support leaders on either side of the line should get their account rep to state, in writing, what the seat floor is today and whether it's scheduled to move.
Should I trust a vendor's growth numbers when comparing platforms?
Treat self-reported ARR and growth figures as marketing, not due diligence — they're defined and measured entirely by the vendor.
Genesys's jump from $2.1 billion to near $2.5 billion in ARR, and its 35% cloud revenue growth, are real numbers but they're Genesys's own accounting of Genesys Cloud, not an independent measure of support-team outcomes like resolution time or agent retention. A vendor doing more deals is not the same as a vendor doing better ones. Before signing, ask any shortlisted provider for reference customers your size, not just the topline growth slide.
What does the end of RingCentral's exclusive Mitel deal mean for buyers?
Mitel customers now have genuine competitive leverage — RingCentral no longer has a lock on the migration path, so rival bids are live.
That's useful only if you use it: get competing migration proposals from at least two vendors before renewing anything with Mitel or its former exclusive partner. Don't assume the incumbent relationship still carries preferential terms.
Is a hybrid option like Avaya Infinity or Cisco's on-prem stance a real alternative to migrating?
Yes for large, complex environments wary of disruption, but it delays rather than avoids the eventual cloud decision.
Cisco's public commitment to on-premise technology and Avaya's Infinity platform both target enterprises uncomfortable with a full cutover. That's a legitimate buy for now, but support teams choosing this route should still ask what their AI roadmap looks like on that architecture — NICE's Cognigy acquisition suggests AI depth is becoming the real differentiator once the migration question is settled, not the deployment model itself.
