Who are AudioCodes competitors?

AudioCodes competes across two adjacent markets: traditional Session Border Controllers and enterprise SBC hardware, and the voice AI layer that connects telephony to conversational AI platforms. The competitors in each market are different. For the voice AI layer specifically (turning AI agents into phone-ready experiences) Seamly is a direct alternative. The difference is in the starting point. AudioCodes extends your existing telephony estate, requires internal telecom expertise, and bridges to your AI platform. Seamly delivers managed voice infrastructure end-to-end, so you don't need an SIP environment or internal telecom team to deploy. If you already have AudioCodes hardware and SIP infrastructure, extending it makes sense. If you're starting with AI agents and want to deploy in 2 to 6 weeks, Seamly is the more direct route.

What is AudioCodes used for?

AudioCodes is primarily known for voice networking infrastructure: Session Border Controllers, SIP gateways, IP phones, and software that connects enterprise telephony estates to platforms like Microsoft Teams. It's an infrastructure-first vendor with deep roots in carrier-grade voice. More recently, AudioCodes extended into voice AI through its VoiceAI Connect product, which bridges existing telephony systems with bot frameworks and speech services. The deployment model assumes you already have SIP infrastructure to extend. Seamly takes the opposite starting point. We provide the full voice layer, with carrier, STT, TTS, orchestration, and EU hosting as a managed service. There's no requirement for existing telephony infrastructure.

What is the best AI voice agent platform?

The 'best' platform depends on what you bring and what you're willing to operate. For teams with existing SIP infrastructure and an internal telecom function, an infrastructure-first product that extends what they have can make sense. For teams starting from an AI agent and a phone number, an intelligence-first managed platform is the faster path. Seamly fits the second case. We deliver managed carrier, STT, TTS, orchestration, EU hosting, and dedicated support as a single layer. Deployment takes 2 to 6 weeks, and the operational burden (monitoring, latency tuning, fallbacks) sits with us. What matters most for 'best' is the match between your team's strengths and the platform's deployment model. Voicification, done well, removes work; it doesn't add a new specialism.

How to make voice AI agents?

A voice AI agent needs different layers: a carrier connection to the telephone network, a speech-to-text engine, a reasoning engine (LLM, rule engine, or both), a text-to-speech engine, and an orchestration layer that handles turn-taking, latency, fallbacks, and call transfers. In an infrastructure-first build, your team selects, integrates, and operates each layer. That's flexibility, and it's also ongoing engineering work, much of it specialist telecom expertise that most product teams don't have in-house. In an intelligence-first approach, a managed platform delivers the carrier, speech engines, and orchestration as a single layer. Your team designs the AI agent itself (what it knows, how it speaks, when it escalates) and the voice infrastructure runs underneath. Seamly is built for this model, with EU hosting and 2-to-6-week deployment.

The Best Parloa Alternative for AI Agents

Add voice without replacing the AI platform behind it

Parloa provides an AI Agent Management Platform where enterprises can design AI agents across voice, chat and messaging. Seamly provides the managed voice infrastructure that connects an existing AI agent or conversational AI platform to telephony.

The difference between the platforms starts with a fundamental question: do you need a platform to build and manage the AI agent, or a voice layer for the AI technology you already have?

Two different roles in the AI stack

Parloa's AMP covers the AI agent lifecycle. Enterprises can create agents, connect them to enterprise systems, test their behaviour, deploy them across channels and monitor performance from the same platform. It also supports bring-your-own STT, TTS and LLM options.

Seamly starts further downstream. The agent logic remains within your existing platform. Seamly connects that agent to the phone network and manages the telephony, speech technology and operational infrastructure required for production voice.

The core differences

AI Agent Management Platform

Parloa brings agent design, integrations, simulations, evaluations, deployment and performance monitoring into one platform. Voice is built into that environment alongside chat, messaging and other customer interaction channels.

Its architecture can therefore take responsibility for a substantial part of the conversational AI stack, from model orchestration to the lifecycle of the agent itself.

Managed voice infrastructure for existing AI agents

Seamly leaves the agent and its intelligence within your current platform. It adds the infrastructure needed to make that agent available over the phone. If you’re building an AI agent platform yourself, Seamly is the right choice if you want to scale to voice.

Telephony, routing, phone numbers, STT, TTS, monitoring and operational support are managed as part of the voice layer.

Build and manage the customer-facing agent

Parloa is built around the full lifecycle of enterprise AI agents. CX teams can create and refine agents, integrate them with systems such as CCaaS and CRM platforms, and deploy them across several customer contact channels.

This model makes sense for organizations looking for an AI agent platform as part of their contact center architecture.

Extend the AI proposition you already have

Seamly starts with existing AI technology. The conversational platform continues to control the agent, workflows, integrations and customer-facing proposition.

Seamly takes responsibility for turning that existing experience into a production voice channel. For conversational AI vendors and system integrators, this means voice can be added without moving the underlying agent into another platform. Plus, you don’t have to build voice AI yourself – we do that for you.

Different pricing models for different deployment approaches

Parloa describes its model as consumption-based, with pricing influenced by factors such as task complexity, interaction volume and deployment requirements. This fits its broader role as an AI Agent Management Platform, where multiple components of the agent are part of the commercial model.

Seamly uses a pay-as-you-go model based on voicebot calls. Partners pay per interaction, so usage scales directly with the number of conversations handled over the phone.

This creates a simple unit to incorporate into their own pricing. Partners can apply their own markup to Seamly's per-call rate and package voice within the commercial model they already use for customers. As call volumes increase or decrease, voice costs move with actual usage rather than requiring a fixed commitment.
