AI Call Cutting Mid-Way? Find the Reason and Fix It, Step by Step

An AI voice agent should end a call only when the conversation is really over. If your calls end early, the reason is almost always one of four things: a time limit set too low, the caller going quiet, the script telling the agent to stop, or a number that cannot be reached properly. This guide shows how to find which one it is in two minutes, and what every advanced setting of a TaskVox agent does, so you can fix it yourself.

Step 1: read the End Reason of the call

Go to Call Logs, open a call that ended early, and look at End Reason in the call details. Also note the call's duration and the last few lines of the transcript.

Step 2: the call always cuts at the same time — Max Call Duration

If many calls end at exactly the same length — one minute, two minutes — and the End Reason is max_duration, the agent is hitting its time limit. Open the agent, then Advanced Settings → Max Call Duration (minutes). It can be set from 3 to 60 minutes; 5 minutes is a good value for sales, follow-up and qualification calls. A short limit does not save money: you are billed for the minutes actually used, and a call cut just before the customer gives their number is a lost lead.

Step 3: the caller went quiet — Silence Timeout

Silence Timeout is the number of seconds the agent waits for the caller to speak after the agent finishes talking. Part-way through that time the agent checks once — "Are you still there?" (in Hindi, "क्या आप सुन पा रहे हैं?"). If the caller still says nothing when the time is up, the agent ends the call. It can be set from 5 to 120 seconds.

• 15–20 seconds works for most sales and follow-up calls.
• 25–30 seconds if callers often need time — to find a document, check with family, or read out a number.
• Too short (5–8 seconds) cuts people who are thinking. Too long keeps a silent line open after the person has already gone, and calls are billed per started minute.

Now read the last lines of the transcript. If the agent asked a long or confusing question and the caller went quiet, the fix is in the script, not the timer: ask one short question at a time, and make sure the caller knows who is calling and why (Step 4).

Step 4: the agent ended the call itself — check the script

An End Reason of completed means the agent decided the conversation was over. That is right when the caller said goodbye or the script reached its closing line. It is a problem only if it happens too early. Check your script for these:

• Clear end rules. Write exactly when to end: "If the customer is not interested, say 'No problem, thank you' and end the call." and "After saying thank you and goodbye, end the call." Then the agent ends cleanly instead of waiting in silence.
• Introduce yourself first. An opening that only asks a question ("Looking for a property?") makes people ask "Who is this?" and hang up. Say your name, company and reason for calling in the first line.
• One question at a time. Short, polite questions keep people talking. Keep Max Words per Response around 30.
• Phone numbers in parts. People often say a number in pieces or as "double five". The agent is instructed to add the pieces up and to read back only a complete 10-digit number before confirming — you can add the same rule to your script.

Step 5: picked up and dropped at once — the number

When a call is picked up and drops before the agent says anything, Call Logs shows No conversation and you are not charged. The usual cause is the number itself. Upload 10-digit Indian numbers (for example 9876543210); +91 or a leading 0 is removed automatically. Numbers that cannot be Indian numbers — foreign numbers, or numbers with a digit missing or extra — are shown in the campaign's Wrong numbers card with the reason and how to correct them, and they are not called.

Step 6: everything looks right — the caller's network

Some calls end because the person's phone lost coverage or they hung up. If only a few calls end early and the transcripts look normal, that is ordinary. Calls that were not answered are retried automatically during the campaign, and you can run another retry round for the rest from the campaign page.

Every advanced setting, explained

Open an agent and expand Advanced Settings. Here is what each one does and a safe starting value.

Outside Advanced Settings, three more parts shape every call: the First Message (what the agent says when the call connects), the Qualification Fields (the details the agent should capture, such as name, phone and budget, which appear on the Leads page) and the optional Lead Scoring Criteria (what Hot, Warm and Cold mean for your business).

A quick checklist before your next campaign

• Max Call Duration is 5 minutes (at least 3).
• Silence Timeout is 15–20 seconds (25–30 if callers need time).
• The first line says who is calling and why.
• The script says when to end the call, after a polite goodbye.
• Numbers are 10-digit Indian numbers, and the Wrong numbers card is empty.
• Make one test call from the agent page and read its End Reason and transcript.

What it costs

TaskVox charges only for answered calls, per started minute — ₹2–₹4 per minute with the phone call included and no monthly fee. Calls that are not answered or drop before the agent speaks are free. See the rate card and calculator.
