"AudioCodes vs Avaya" is a search that usually hides a category confusion: these companies mostly sell different things. AudioCodes builds voice infrastructure — session border controllers, media gateways, phones, and Teams/Zoom connectivity services. Avaya builds full communications platforms — unified communications and contact center software for large enterprises. Sometimes they compete, often they complement each other, and occasionally the real question is whether you need either. This page sorts it out.
AudioCodes vs Avaya at a Glance
The short version: Avaya is a platform vendor — UC and contact center software with a large installed enterprise base. AudioCodes is an infrastructure and enablement vendor — the SBCs, gateways, and connectivity services that sit between your phone system and the outside world, especially in Microsoft Teams and Zoom environments. Neither publishes list pricing for enterprise deals; everything is quoted through channels and partners, so written quotes are the only real comparison.
| AudioCodes | Avaya | |
|---|---|---|
| Core category | Voice infrastructure: SBCs, media gateways, IP phones, meeting devices, voice connectivity services | Full-stack platforms: unified communications, contact center (on-prem, private cloud, and CCaaS) |
| Flagship strengths | Certified SBCs for Microsoft Teams Direct Routing and Zoom Phone; SIP interop; analog/digital migration gateways | Enterprise UC (Aura/Communication Manager heritage) and large-scale contact centers (Avaya Experience Platform) |
| Typical buyer | IT teams connecting Teams/Zoom to the PSTN, migrating legacy PBXs, or securing SIP trunks | Large enterprises running — or modernizing — an Avaya UC/CC estate |
| Deployment model | Hardware appliances, virtualized/software SBCs, and managed services | On-prem, private cloud, subscription (Avaya Experience Platform), hybrid |
| Pricing approach | Per-device/per-session licensing plus services; partner-quoted | Subscription or perpetual licensing plus maintenance; partner-quoted |
| Best fit | Teams/Zoom-centric organizations needing certified voice infrastructure | Enterprises with deep Avaya investments, complex contact centers, or hybrid cloud timelines |
What Each Company Actually Sells
AudioCodes has spent three decades on the plumbing of enterprise voice. Its session border controllers are among the most widely certified for Microsoft Teams Direct Routing and Zoom Phone, its media gateways bridge legacy analog and digital equipment (fax machines, elevator phones, old PBXs) into SIP environments, and its managed services wrap that infrastructure for organizations without deep voice engineering staff. If your question is "how do I connect my phone system to the PSTN, securely and reliably," AudioCodes is a canonical answer.
Avaya is one of the original enterprise communications vendors, with an enormous installed base of Aura and Communication Manager systems and a contact center franchise serving many of the world's largest service organizations. Its current strategy centers on the Avaya Experience Platform — contact center and UC delivered as cloud subscription — while continuing to support and modernize its on-prem base. Avaya went through financial restructuring in 2023, emerging with reduced debt; buyers evaluating long-term platform commitments should weigh that history and the company's current financial posture as part of due diligence, as they would with any vendor.
Where They Compete — and Where They Don't
The genuine overlap is narrower than the search volume suggests. They compete when an Avaya shop is deciding whether to stay on Avaya's stack or migrate to Microsoft Teams/Zoom for UC — in which case AudioCodes infrastructure often anchors the Teams path. They also meet in contact center adjacency: Avaya sells the platform; AudioCodes sells the voice connectivity and AI-adjacent voice services that feed it. In a great many deployments they coexist: an Avaya contact center behind AudioCodes SBCs is a common architecture. Choosing between them as if they were interchangeable products leads to bad designs.
Pricing Approach
Neither vendor sells enterprise deals off a public price list. AudioCodes prices SBCs and gateways by capacity (sessions) plus software options and support contracts, typically through resellers — and the same hardware can be quoted at meaningfully different prices by different partners. Avaya's subscription and maintenance pricing depends on seat counts, feature tiers, migration credits from legacy estates, and negotiation. In both cases the channel matters: an experienced advisor or reseller with volume relationships usually secures better terms than a one-off direct inquiry. Verify current pricing, support renewal rates, and end-of-sale/end-of-support timelines in writing for any hardware or software you're quoted.
Support, Roadmap, and Risk
AudioCodes' risk profile is that of a stable, focused infrastructure vendor — the main diligence items are product lifecycle timelines and whether managed services or your own team will operate the SBCs. Avaya's diligence is heavier: platform roadmap commitments, the pace of its cloud transition, the support experience for on-prem estates, and vendor financial health all deserve direct questions. For either vendor, insist on documented escalation paths and, for voice-critical environments, a support tier that matches your uptime requirements — voice infrastructure is the thing nobody notices until it stops working.
Which One Do You Actually Need?
AudioCodes fits when: you're deploying Teams Phone or Zoom Phone and need certified Direct Routing SBCs; you're migrating a legacy PBX and have analog/digital devices that must survive the transition; or you need carrier-grade SIP interop and security at your network edge. Avaya fits when: you have a substantial Avaya estate whose modernization path runs through the Avaya Experience Platform; you run a large, complex contact center where Avaya's depth matters; or regulatory/operational constraints keep you on-prem or in private cloud longer than the market's cloud-first narrative assumes. Neither fits when: your real need is a modern cloud UC/CC platform and neither legacy estate nor specialized infrastructure applies — in which case the right comparison is among CCaaS/UCaaS platforms, not these two names.
