I do not believe it supports PTT. But, if it does, look in the motherboard bios. If you cannot find it there, it does not have PTT.

In theory, this processor is capable of supporting PTT, but (a) ARK.INTEL.COM is not saying, one way or the other (thanks Intel) and (b) this is dependent upon what firmware is being run on the ME and whether the PTT capability is supported by the motherboard's BIOS.
Bottom line, we can't really answer your question. We would need a lot more information about your motherboard. It may be easiest to just ask the motherboard manufacturer.
Hope this helps,
