Meet Inextrix at Africa Tech Festival 2026, Cape Town! Let's discuss your next telecom project.
Callers should not have to keep pressing numbers to get help. We build intelligent, speech-driven IVR systems that understand natural conversations and work with FreeSWITCH, Asterisk, OpenSIPS, or the SIP stack you already use.
FreeSWITCH
Asterisk
OpenSIPS
We build custom conversational IVR systems from the ground up. No templates or off-the-shelf platforms.
Our systems are designed to handle real calls in real telecom environments. They combine natural language processing, speech recognition, and AI-driven routing with your existing VoIP stack.
Here’s what we can build:
Natural language call handling over SIP/RTP
NLP and intent recognition engine integration
Custom speech recognition and TTS pipelines
Multi-turn conversation flow design
DTMF fallback support for callers who prefer keypad input
Real-time CRM data lookup during live calls
Multi-language and multilingual IVR support
Omnichannel support across voice, SMS, and chat
Your customers don’t care how many features you have when the system isn’t reliable.
Modernize your legacy IVR without changing your core telephony stack.
Reduce agent workload by letting the IVR handle tier-1 calls automatically.
Add conversational IVR as a billable feature that delivers more value to your customers.
Build smart call handling into your product from the start instead of adding it later.
Reduce call abandonment and handle routine queries without sending every caller to a live agent.
Automate routine customer calls, improve service efficiency, and help agents focus on complex customer interactions.
World-class development, customization, and support designed around your business outcomes, not individual features.
Custom dialplan logic, ESL-based NLP hooks, and real-time AI routing built directly into FreeSWITCH.
AGI/AMI-based conversational flows, custom dialplan scripting, and speech recognition built into the infrastructure.
We work with Dialogflow CX, Rasa, AWS Lex, and Google CCAI. We choose the engine based on your architecture and requirements.
ASR options include Deepgram, Google STT, Whisper, and AWS Transcribe. For TTS, we work with ElevenLabs, Polly, and Google TTS based on your call volume and language needs.
Handle inbound calls through standard SIP trunks and PSTN without relying on proprietary gateways.
Provide browser-based conversational IVR for web self-service portals.
Pull real-time caller data from Salesforce, Zoho, and HubSpot while the call is in progress, not after it ends.
Implement secure call flows, access controls, and data protection measures aligned with your business and regulatory requirements.
Track call flows, IVR performance, and interaction outcomes to identify issues and improve the caller experience.
Replace DTMF menus with NLP-driven conversational flows and make it easier for callers to get help.
Automate tier-1 queries, understand caller intent, and route calls to the right agent with the necessary context.
Let users manage billing, account queries, and support requests without waiting for a live agent.
Use natural language for appointment reminders, payment alerts, surveys, and other outbound calls.
Build NLP flows in multiple languages for international VoIP and telecom operations.
Create a consistent customer experience across voice, SMS, and messaging channels.
Most traditional IVR systems were built around keypad menus. Callers had to listen to several options, remember the right one, and press a button. If they missed an option, they often had to start over.
Conversational IVR makes this easier. Callers can simply speak naturally and explain what they need.
| Feature | Traditional IVR | Conversational IVR |
|---|---|---|
| Input | DTMF keypress | Natural speech |
| Caller Experience | Rigid menu trees | Free-form conversation |
| Intent Handling | Fixed options only | NLP-driven intent recognition |
| CRM Integration | Limited or none | Real-time data lookup |
| Scalability | Static | Dynamically scalable |
The difference can be seen in call abandonment, agent workload, and the overall caller experience.
We review your existing IVR flows, identify where callers drop off, and define the NLP scope before development starts.
We choose the NLP engine, ASR/TTS stack, and integration points based on your existing infrastructure and requirements.
We map intents, entity extraction, fallback handling, and escalation paths to support real-world caller behavior.
We build and integrate the system on FreeSWITCH, Asterisk, or your existing stack. Our developers manage the complete development process.
We test ASR accuracy, latency, load, and system performance before deployment.
We deploy the IVR system, set up monitoring, provide documentation, and train your team.
After deployment, we review conversation analytics, improve flows, and add new features as needed.
Monitor call quality, response times, and system reliability to identify issues early and maintain consistent IVR performance.
