when i make an outbound call and the customer doesn't pick up, vapi makes the call again, by itself. @Shubham Bajaj, kindly. i can't be the only one facing this issue.

Hi there! 👋 I understand you're experiencing an issue where Vapi makes a second call automatically when the customer doesn't pick up the first one. While I don't have the exact reason for this specific behavior in your case, I can definitely help with what I know about this issue. Good news - you're definitely not the only one facing this! According to information I found, other users have reported the same problem. In fact, a user named ml_futures mentioned having the exact same issue in a Discord thread [here](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1313293840580612166). The most promising solution I found comes from Shubham Bajaj (who you tagged), who suggested setting

endCallFunctionEnabled

to true in the dashboard. This setting might prevent the automatic redial behavior you're experiencing. If you want to try a more technical approach, I also found that Vapi has a

backoffPlan

configuration with

maxRetries

and

baseDelaySeconds

settings that control retry behavior. Setting

maxRetries

to 0 might prevent automatic retries:

json
"backoffPlan": {
  "maxRetries": 0,
  "type": {
    "key": "value"
  },
  "baseDelaySeconds": 1
}

This issue might also be related to how Vapi handles voicemail detection. When a call isn't answered, Vapi's behavior depends on various settings including voicemail detection configuration. Is there anything else you'd like to know about this issue or would you like more details on any of these potential solutions? Sources: - [Discord Thread about the same issue](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1313293840580612166) - [Vapi API Reference Calls List](https://docs.vapi.ai/api-reference/calls/list)

Do you have the call IDs where VAPI is making the calls by itself instead of being initiated by you? If not, you can also share the organization ID with the date/time range, and I'll take a look.

Org ID: 3d53b8d2-24e0-47fe-9b81-ba23d3611d20 date and time range: Wednesday 26th march, 1900hrs-0000hrs, berlin time.

Okay, I looked into the call of all IDs given the date time range, and all of them are on the same phone number. Went to almost same number, and for sure not done by us. Eventually either done by you or done by somebody else. So check in your system who is triggering whose calls. In case required, we can share IP addresses as well. https://cdn.discordapp.com/attachments/1354534850870382732/1355544094918840360/Screenshot_2025-03-29_at_7.36.52_PM.png?ex=67e95051&is=67e7fed1&hm=dbcbca77de537309fb550559bf80bf1f24351482663edce4e5265602649ab4ea&
