What AI development services does CelloIP offer?

CelloIP Technologies offers AI development services including Voice AI agent development (GPT-4, Claude, Llama 3 with Whisper ASR and ElevenLabs TTS), LLM integration into existing VoIP systems, NLP-powered IVR, real-time call analytics, and conversational AI chatbots. We have delivered 30+ AI-enhanced communication systems.

Can CelloIP integrate AI into my existing VoIP system?

Yes. CelloIP integrates AI into existing Asterisk, FreeSWITCH, Kamailio, and cloud-based VoIP systems using AGI/ESL hooks, WebSocket event streams, and REST APIs. We have integrated GPT-4, Claude, Whisper, Deepgram, ElevenLabs, and Cartesia into production telephony environments.

What is the cost of AI VoIP integration?

AI VoIP integration projects cost $15,000–$80,000 depending on the number of intents, languages, integration points, and whether on-premise LLM deployment is required. CelloIP offers fixed-price AI integration packages and dedicated AI developer retainers from $25/hr.

CelloIP Technologies is an AI development company specialising in LLM integration, voice AI agents, RAG pipelines, and conversational AI systems. We build custom AI solutions using GPT-4o, Claude 3.5 Sonnet, and Gemini — integrated with your existing VoIP and telephony infrastructure. Services include voice bot development, AI IVR replacement, NLP systems, and ML infrastructure on Kubernetes. Based in India, serving clients globally.

Frequently Asked Questions

Common questions about our AI development approach.

What AI development services does CelloIP offer?+
CelloIP offers end-to-end AI development including LLM integration (GPT-4o, Claude, Gemini), voice AI agents and voice bots, RAG (Retrieval Augmented Generation) pipelines, conversational AI and NLP systems, AI-powered IVR replacement, custom ML model development, and AI infrastructure on Kubernetes. We specialise in AI systems that integrate with VoIP and telephony infrastructure.
How do you integrate LLMs like GPT-4o into existing systems?+
We integrate LLMs via API (OpenAI, Anthropic, Google) or self-hosted open-source models (Llama 3, Mistral, Phi-3). Integration typically involves: designing the prompt system and conversation state management, building a RAG layer for context grounding, connecting to your existing data sources (CRM, ticketing, knowledge base), and deploying with proper rate limiting, cost controls, and fallback logic. The entire pipeline is observable via LangSmith or similar tooling.
Can you build AI systems that work with our phone/VoIP system?+
Yes — this is our specialty. CelloIP combines AI development with deep VoIP expertise. We build voice bots that integrate with Asterisk, FreeSWITCH, LiveKit, and any SIP infrastructure. This includes AI IVR replacement, outbound calling bots, real-time transcription during calls, post-call summarisation, and sentiment analysis — all connected to your existing phone system.
