No.

According to the SIP RFC, a SIP endpoint is supposed to respond to an
OPTIONS message the same way that it would respond to an INVITE message
with the identical destination, but I've never seen a phone respond to
an OPTIONS message with anything but '200 OK', even when a redirect
(forward) is in place.

So, the alternative option is to play with html and use phone embedded html
server to get this redirection data.
