@AI Evy why am i getting a lot of inbound calls to my retell agent that does not connect? When i view the call logs, it says the call duration was 0:00? I received 9 inbound calls like this recently, all from numbers that belong to our customers. After digging further, I found one of our outbound agents tried to call one of our customers back but it didnt work with a 0:00 duration. However, when I call any of the numbers manually from my cell to the customers cell, it connects without issue? Why is this happening? We use Retell provided phone numbers within the dashboard Here is the copy & pasted data from the call log from one customer who called our inbound agent: 2/19/2025 15:12 phone_call Agent: Inbound Calls (out-of-hours) - LIVE ( agent_5f6024...288 ) ∙ Version: 100 Call ID: call_395f46883116effeafc...9af Phone Call: +14696157027 → [my retell inbound phone number] (Inbound) Duration: 12/19/2025 15:12 - 12/19/2025 15:12 EST Cost: $0.000 Conversation Analysis Rerun Preset Analysis Call Successful Unsuccessful Call Status Ended User Sentiment Unknown Disconnection Reason User_hangup Transcription Data Detail Logs View In Test Playground No transcript. AFTER THAT, ONE OF OUR OUTBOUND AGENTS ATTEMPTED TO CALL HIM AND IT SAYS THIS: 12/21/2025 20:23 phone_call Agent: MVA OB - TEXAS = LIVE ( agent_7b38df...d1d ) ∙ Version: 34 Call ID: call_4e0c5b6f029c02c7e83...15e Phone Call: [my retell outbound phone number] → +14696157027 (Outbound) Duration: 12/21/2025 20:23 - 12/21/2025 20:23 EST Cost: $0.000 Conversation Analysis Rerun Preset Analysis Call Successful Unsuccessful Call Status Not_connected User Sentiment Unknown Disconnection Reason Dial_no_answer Transcription Data View In Test Playground No transcript.

Thanks for tagging me @sw2026sw. I'll look through relevant sources and get back to you shortly.
### Answer Based on your call logs, here's what the disconnection reasons indicate: Inbound call (0:00 duration) : The
disconnection_reason
shows
user_hangup
with
call_status: ended
— this means the caller hung up before the agent could connect or respond. [(1) ]() , [(2) ]() Outbound call (0:00 duration) : The
disconnection_reason
shows
dial_no_answer
with
call_status: not_connected
— this means the call was dialed but the recipient didn't answer. [(1) ]() , [(2) ]() Why this might be happening: 1. Inbound calls with immediate hangups: Customers may be hanging up quickly before the agent responds (possibly due to latency or they changed their mind) . The
user_hangup
reason confirms the caller ended the call. [(1) ]() 2. Outbound calls not connecting: The
dial_no_answer
indicates the recipient's phone rang but wasn't answered. This could be due to: - The customer not recognizing the outbound number - Calls being blocked or sent to voicemail - Network/carrier issues on the recipient's end Troubleshooting steps: - Check if your outbound phone number has proper caller ID configured so customers recognize incoming calls [(3) ]() - Verify your phone numbers have the correct
inbound_agent_id
and
outbound_agent_id
bound , [(4) ]() Unfortunately, I don't have specific documentation on diagnosing carrier-level issues or spam blocking. For deeper investigation, you may want to: - Visit [Contact Sales](
