BUG: 13.98% of Inbound Calls Not Answered With ‘0:00’ Duration

Hi Retell team,

I have a client in the legal space who is using an agent to answer out-of-hours inbound calls.

However, we have noticed a significant portion of these calls (13.98%) are not being answered.

The agent never connects/speaks, and they get logged with a ‘0:00’ duration.

Can you please let us know why this is happening?

We have verified that these are legitimate inquiries from current clients & new inquirers, who their team has no problem calling/connecting with when they call them back.

Due to the nature of the industry, this is costing the client to lose out on a lot of high-value enquiries, and we are at risk of losing them because of this problem.

Thank you.

Hey @developers

Thanks for sharing the call ids. I’ve escalated this to our team for further review.

We’ll update you as soon as we hear back.

Best regards

Thanks @shaw, appreciate it

Hey @developers

We’ve looked into all 26 call IDs you provided.
In 25 of 26 cases, the caller’s side disconnected within a fraction of a second (200ms–1s) — before our agent could even pick up. Our system responded correctly and was ready to answer, but the incoming call was cancelled before the connection completed. This is why these show as 0:00 duration, and also why your team has no trouble reaching the same callers when calling them back.
These ultra-fast disconnects aren’t human hangups — they point to something on the caller’s carrier or forwarding chain dropping the call before it reaches our agent.
The remaining 1 call was an isolated internal error, unrelated to the pattern above.

We’d recommend:

  1. Checking with your client’s phone provider — they should investigate why inbound calls are being dropped within <1 second.

  2. If call forwarding is used to route calls to the Retell number, verifying that the forwarding setup isn’t timing out or causing issues.

Thank You
