Call log api request for ALL associated extensions

Is it possible to query the api for the call log and retrieve the logs for ALL associated extensions? As it stands now, I have to make a separate call for each extension to get all the logs. I see the option to filter by a single extension, but I don't believe I saw the option for all extensions in the parameters for the call log api. But perhaps I am missing something? Is there maybe a certain keyword I can use for the extension parameter that will give me all extensions?
