Objective
This article helps you raise the maximum length of a call on your account from 4 hours to 24 hours, for use cases where calls need to stay up far longer than the default.
Product
Programmable Voice
Environment
Twilio Console
User Account Permission/Role(s) Required
Read access to Voice settings is required to view the page. Update access to Voice settings is required to change the setting — without it the toggle is read-only.
Procedure
- In the Twilio Console, select Communications in the left sidebar.
- Select Voice, then Settings.
- On the General tab, Calls & Conferences is selected by default.
- Find the 24-hour maximum call duration section.
- Switch on Enable 24-hour maximum call duration.
- A confirmation message reads "Voice general settings have been updated successfully."
Additional Information
- The change is saved as soon as you switch the toggle — there is no separate Save step.
- When the setting is enabled the maximum call duration is 24 hours. When it is disabled the maximum is 4 hours.
- The setting applies to both Programmable Voice and Elastic SIP Trunking calls.
- Switch the toggle off again to return to the 4-hour maximum.
- Voice settings are also reachable from Settings in the left sidebar, under Product settings › Voice.
