JVoiceXML vs Teloz IVR

JVoiceXML is a free, open-source VoiceXML interpreter for Java, described by its project as implementing VoiceXML 2.1. It supports dialogs that combine synthesized speech or digitized audio with spoken or DTMF input. Dialog functions also include recording, telephony, and mixed-initiative conversations. The architecture allows custom extensions, and demo implementation platforms support Java APIs such as JSAPI and JTAPI. The repository includes modules for Mary, MRCPv2, JSAPI 2.0, JTAPI, and text implementations. The project names platform independence as a major goal. Its repository identifies the license as LGPL-2.1 and provides release downloads. The latest listed version is 0.7.8, which added an SRGS grammar processor with SISR support, Microsoft LUIS as a grammar processor, bug fixes, and a move to Gradle. JVoiceXML is listed for API, Linux, and self-hosted use.

Teloz IVR routes callers through multi-level voice menus using NLP voice recognition and DTMF input. Its visual drag-and-drop flow builder is intended for operations teams creating or changing call flows without code. Nested prompts can branch according to time of day, language, and caller location, and a CRM lookup can inform routing. DTMF can also serve as a fallback to voice recognition. The product lists analytics on each IVR node. Teloz says it encrypts data in transit using TLS 1.3 and SRTP, and data at rest with AES-256. Every plan includes SAML 2.0 SSO, SCIM 2.0 provisioning, MFA, role-based access, and tamper-evident audit logs. A 14-day trial includes every feature and does not require a credit card. The free plan includes 100 US/Canada calling minutes, 50 SMS segments, one local DID, and 25 AI receptionist minutes per month. Paid plans are Starter at $7.99 a month per user, Professional at $15.99 a month per user, and Enterprise at $25.99 a month per user. The service is available on web, iOS, and Android.
