If you’re leaving Avaya, shortlist by what you need to replace: enterprise contact center, business calling, or an older on-prem setup. Avaya’s listed starting price is $19.99; these alternatives start at $15 for Dialpad and Nextiva and reach $119 for Five9, while 8x8 pricing is not published. That is not a like-for-like quote comparison. Reddit commenters raise concerns about product direction, subscription increases and contact-center competitiveness, but their reports do not show that every Avaya deployment is at risk.
01Why people leave Avaya
Uncertainty about product direction
One Reddit commenter said ACO was canceled and described IP Office as Avaya’s remaining major line; treat that as a user report, not a company update.
Subscription price concerns
A commenter said customers were tired of subscription changes and rate hikes. That is an individual report, not a universal billing outcome.
Contact-center competitiveness concerns
One commenter said Avaya contact-center products were behind and described large customers leaving; it is an anecdote, not a market-wide measurement.
02The alternatives, ranked by fit
- Large contact centers
Five9Five9Five9 is the most direct fit in this list for a large Avaya contact center evaluating multiple channels, AI self-service, workforce tools and analytics. Its listed starting price is $119, far above the other options here, so compare a full quote and the capabilities you actually need before switching. User reports also raise reliability concerns.
Trade-off: The high entry commitment and reported reliability concerns deserve scrutiny.
6.3/10from
$119/mo - Broad communications
8x88x8Consider 8x8 if you want to compare a broad business communications suite rather than only a phone system. The listing includes calling, meetings, messaging and contact-center tools, which may suit organizations reviewing several Avaya workloads together. Its price is not published, so you will need a quote to judge cost against your current setup.
Trade-off: Pricing is quote-only, so there is no published starting price to compare.
6.0/10from
Custom - Flexible deployment
3CX3CX3CX is worth comparing if your replacement needs flexible deployment, contact-center features or per-system licensing. Those are the specific strengths in its listing, and its starting price is $25. That makes it a candidate for teams that do not want to choose solely between keeping Avaya and buying a high-entry-cost contact-center product.
Trade-off: The listing flags extra hosting costs and partner concerns.
5.6/10from
$25/mo - Voice and collaboration
DialpadDialpadDialpad fits teams looking to consolidate voice and collaboration, or support and sales teams that want AI call tools, coaching and dialing. Its listed starting price is $15. That makes it a lower-entry-price option to investigate, but compare a full quote and the support experience before treating it as an Avaya replacement.
Trade-off: Check the full quote and support experience before switching.
6.8/10from
$15/mo - Customer channels
NextivaNextivaNextiva is a candidate if the Avaya project is part of a broader effort to consolidate customer channels or add AI conversation handling. Its listed starting price is $15, and the listing also calls out annual-billed plans for small teams. Check the actual plan and billing terms against the workflows you need to move.
Trade-off: Costs and user reports about support deserve scrutiny.
6.3/10from
$15/mo - CRM-connected calling
AircallAircallAircall is a narrower option for teams whose main need is CRM-connected business calling, call automation or shared conversations for distributed teams. The listing puts its starting price at $30 and highlights calling and AI tools. It is better suited to evaluating those needs than assuming it replaces every part of a complex Avaya environment.
Trade-off: Add-on costs and mixed support reports temper the case.

Questions people ask
Does the company Avaya still exist?
The Reddit threads we read describe Avaya customers and ongoing IP Office use. One commenter said a new IP Office chassis was expected in the first half of 2027, but that is a user report, not an official company-status update. Check Avaya’s current announcements before making a procurement decision.
Who are Avaya's competitors?
Options in this comparison include 3CX, Dialpad, Nextiva, Five9, Aircall and 8x8. They suit different needs: Five9 is listed for large, multi-channel contact centers, while Dialpad targets voice and collaboration. Compare by workload and quote; the listed starting prices range from $15 to $119, and 8x8 pricing is not published.
Who services Avaya phone systems?
The Reddit threads we read mention Avaya business partners and technicians, but they do not identify a current service directory or certify specific providers. Ask Avaya or your existing reseller about coverage for your exact platform, support contract and location before changing systems.
