[Serusers] ATA 186 Behind NAT

I was reading about the ATA186's ability to detect that it is behind a NAT.
It requires that:

"For the Cisco ATA to automatically detect its presence behind a NAT, the
SIP proxy server
or remote user agent server must include the "received=" parameter in the
Via header in the
responses to the Cisco ATA if the proxy detects that the source address and
port do not match
those in the Via header."

Does SER support it?
