Callab AI is an AI voice agent platform purpose-built for complex enterprise telephony environments, integrating natively with legacy infrastructure like Cisco Unified Communications Manager (CUCM) and SIP trunk systems alongside modern cloud contact centers. Many enterprise voice AI platforms are designed for greenfield cloud-native deployments and struggle to integrate with the legacy telephony infrastructure that large enterprises — particularly those with long-established call center operations — still rely on. Callab AI addresses this gap by building native compatibility with both legacy and modern telephony systems, making AI voice agent deployment feasible for enterprises that cannot or do not want to replace their existing infrastructure. The platform targets enterprise organizations exclusively and supports on-premise deployment, differentiating through its deep technical compatibility with the complex, hybrid telephony environments common in large enterprises.

Key Features
- Legacy telephony integration: Integrates natively with legacy enterprise telephony systems including Cisco CUCM, enabling AI voice agent deployment without requiring infrastructure replacement.
- SIP trunk compatibility: Supports SIP trunk infrastructure directly, covering a widely used enterprise telephony standard that many voice AI platforms do not natively support.
- Modern cloud contact center integration: Also integrates with modern cloud-based contact center platforms, supporting enterprises with hybrid or fully modern telephony environments.
- Enterprise-scale voice AI agents: Deploys AI voice agents capable of handling the call volume and complexity requirements of large enterprise telephony operations.
- On-premise deployment option: Supports on-premise deployment for enterprises with strict infrastructure or data residency requirements that preclude cloud-only solutions.
- Multi-model architecture: Uses multiple underlying LLM providers to power the voice agent’s conversational and reasoning capabilities.
Use Cases
- For large enterprises with legacy telephony infrastructure: A large enterprise running Cisco CUCM and SIP trunk infrastructure that cannot feasibly migrate to a cloud-native phone system uses Callab AI to deploy AI voice agents that work directly within their existing telephony environment.
- For enterprises with hybrid contact center environments: An organization operating a mix of legacy and modern contact center technology uses Callab AI to deploy voice agents consistently across both environments rather than needing separate solutions for each.
