Are there any updates on assistants being able to navigate IVR? I.e. using DMTF to select options in a menu? This is a significant blocker for our completion rates. Would majorly appreciate a solve! 🙏

Hi there! 👋 I understand your frustration with IVR navigation using DTMF - this is indeed a known issue that's affecting completion rates for several users. Here's the current status: Current DTMF Functionality: - Vapi does provide a

dtmf

function designed to enter digits on IVR keypads [(source)](https://docs.vapi.ai/tools/default-tools) - However, there are issues with delayed playback of DTMF tones, causing IVR systems to not register them in time [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1338841147077820487) Recommended Workaround: The current recommendation is to use Twilio Flex for IVR navigation and then transfer the call to Vapi [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1338841147077820487). This is because: - Vapi can currently send DTMF tones but not reliably receive them - Twilio Flex handles the initial IVR navigation more effectively Timeline for Improvements: There have been discussions about potential fixes targeted for Q1 2025 [(source)](https://discord.com/channels/1211482211119796234/1211483291191083018/1341097150339350548), but I couldn't find confirmation of any newly released features specifically addressing this issue. I understand this is a significant blocker for your completion rates, and I'll make sure to update you if I learn about any new developments on this front! 🚀 Sources: - [Vapi Default Tools Documentation](https://docs.vapi.ai/tools/default-tools) - [Discord Discussion on DTMF Issues](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1338841147077820487) - [Discord Discussion on Potential Timeline](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1341097150339350548)

I've created a ticket for it and will keep you updated.

@Shubham Bajaj any sense of timeline or priority? I've been following the existing tickets for about a month

Hi,  We currently don’t have a DTMF feature available, but it is on our roadmap. Could you share more about your specific use case?

It looks like you do have a DTMF tool available, it just doesn't work? We have outbound calling agents who encounter IVR menus frequently and they aren't able to engage with them. The agents are able to navigate them, but the DTMF feature doesn't seem to work. https://cdn.discordapp.com/attachments/1349188957442670643/1351319849531473941/Screenshot_2025-03-17_at_3.20.16_PM.png?ex=67d9f22e&is=67d8a0ae&hm=a557f7d117d8b0cefec2cebc4ef2481d5982244bfa08a704d2a5fceb5165d1fc&

I see, thanks. It is showing in the tool section but doesn't work properly. Can you send an sample number where we can test this IVR navigation flow?

Wouldn’t you have internal test numbers and sandbox environ for this? @Shubham Bajaj - can you confirm that Sahil is part of the Vapi team?

@PM6852 Hey, @Sahil is our Founding Solution Engineer at Vapi, and my senior associate as well.

@Shubham Bajaj has anyone done this successfully? We've gotten as far as having Twilio enter a DTMF tone, but there are still a bunch of bugs with that as well.

Hey! To help track down this issue, could you share: - The call ID - What response you expected to get - What response you actually got instead This would really help us figure out what went wrong!
