No but I've asked on the Asterisk-users mailing list and got a response
from a bloke a Digium basically saying that chan_sip doesn't need to
deal with hook flashes because "has its own (more reliable) methods of
signaling." Which basically means they expect phones to deal with
transfers and call hold rather than Asterisk dealing with it.

All is not lost however, proper hold and transfer support is coming to
the S450IP with a firmware release which will hopefully happen in the
next month. I'll post up on this newsgroup when it's available.

cheers,
Paul.
