TekIVR - 2026 Pricing, Features, Reviews & Alternatives

TekIVR is an on-premises SIP (RFC 3261) Interactive Voice Response system for Windows, targeting internet and telecommunications service providers, OEMs, channel partners, and enterprises that require a self-hosted IVR solution. It handles inbound call routing through user-defined scenarios built with a built-in scenario editor, supporting DTMF and speech input, Text-to-Speech output, voicemail with email delivery, call transfer, extension presence checking, and an MRCPv2 proxy for connecting to cloud-based TTS and ASR services. The platform has been tested across Windows Vista, 7, 8, 10, 11, and Windows Server 2008 through 2022.

TekIVR supports a broad range of speech engine integrations for both TTS and ASR, including SAPI, Google Cloud Speech API, Azure Cognitive Services, ElevenLabs API, and Amazon Polly (via SAPI). Automatic Speech Recognition is available through SAPI, Google Cloud Speech API, Azure Cognitive Services, and MRCPv2. SSML is supported for prompt definitions. The MRCPv2 proxy mode bridges MRCPv2-based application servers to SAPI, Azure, and Google Speech engines and requires a commercial license. Multi-server registration allows simultaneous connectivity to multiple SIP servers, and call transfer is handled via SIP REFER (RFC 3515), Bridge, or DTMF (RFC 2833). Codec support covers ITU G.711 A-law/Mu-law and G.722, with UPnP available for NAT traversal.

AI capabilities are available through OpenAI real-time API integration via a Chat action in IVR scenarios, supporting configurable system instructions, function mappings such as transfer_call and query_order, and HTTP GET or batch file execution triggered by AI-driven call events. ElevenLabs AI Agent bridging routes calls to an ElevenLabs-hosted AI voice agent over SIP. Lync/Skype for Business presence status can be queried via an Execute action, allowing scenario branching based on client availability. A freeware tier supports up to 2 simultaneous SIP calls; a commercial license unlocks MRCPv2 proxy functionality and additional capabilities.
