# 13216: Invalid timeLimit value

Log Type: APPLICATION

Log Level: WARNING

## Description

This warning appears when your `<Dial>` verb includes a `timeLimit` value that is not a positive integer in seconds. Use `timeLimit` to set the maximum duration of the `<Dial>`. If you omit `timeLimit`, Twilio uses the default limit of 14400 seconds, or 4 hours.

### Possible causes

* The `timeLimit` attribute is set to `0`, a negative value, or an empty value.
* The `timeLimit` attribute contains a decimal value instead of a whole number of seconds.
* The `timeLimit` attribute includes non-numeric characters or a malformed string.
* Your application generates TwiML dynamically and passes an invalid value into the `<Dial>` verb.

### Possible solutions

* Set `timeLimit` to a positive integer in seconds, such as `timeLimit="120"`.
* Validate any user input or application variable before you add it to the `<Dial>` verb.
* Convert dynamic values to a whole number before returning TwiML to Twilio.
* Remove `timeLimit` if you want Twilio to use the default call limit.
