CallObject / Call Object Identifier field - meaning


There is confusing documentation about what this field means.

The current SF API doc ( "Name of a call center."

However there are other Salesforce sources such as this blog post ( that say it is an identifier for the phone call. Also the label "Call Object Identifier" sounds more like an identifier for the call. And some managed packages e.g Contact World  ( populate it with a unique identifier for the call. 

So is it actually the Call Center ID or the call record ID or it just depends on what software is populating the field?

Hi Eskin,
The Call Object Identifier field is used in CTI functionality  of salesforce to  store the Unique Id for a particular interaction(Call) in the third party Caas system utilising the CTI  so it acts like a record ID for the other system in case you need to compare data between the third party and salesforce activity.Hope that answers your question.
