Calls Module: Minimum duration?

I want to be able to update a Call record without having to set a duration.

I am using an SMS integration, and incoming SMS are created as Calls. To help myself filter out SMS records, I update them as “Received” for the status.

The problem is that by default, Suitecrm won’t let me update a Call record while the duration is “0:00”.

Is there a way to set the Call minimum duration to “0:00” so that I don’t have to update that field every time?

If I understand you correctly you can make default value for the field ‘duration_minutes’ as ‘0’. You can do it to use Studio or manually.
