The Syllable Agentic Platform comes with many useful tools pre-installed.

​
dtmf

Enables your AI Agent to navigate touch-tone phone systems by transmitting RFC 4733 compliant DTMF tones. This functionality is particularly valuable for outbound use cases where your agent may reach IVRs during outreach such as marketing, surveys, or sales calls. When combined with voice-based IVR navigation, it equips your AI Agent with the full range of capabilities needed to operate effectively in outbound scenarios.
