w52 and IP Direct Auto Answer

[asinshesq]

It seems like all of Yealink's voip phones (e.g. T20, T46g, W52) allow the user to make calls to other Yealink extensions by dialing the direct IP address of the target extension, but only the wired phones (e.g. T20 and T46g) have an option to auto answer calls made via direct IP dialing (e.g. see the option in the Features/General Information tab for the T20 to enable "IP Direct Auto Answer"). Is there a way to turn that option on for W52 wireless phones too (so that a direct IP call to a W52 would autoanswer like an intercom call does)?
