I have many C460IP's on asterisk boxes - not trixbox and call transfers
are working just fine.

Looks very familiar

I'd go in and manually check the extensions.conf file(s) generated by
trixbox to make sure they really do have the Tt options in the dial
instructions. (I don't use trixbox, so not much more help than this
though)

I'd also set the C460's to use rfc2833 for tones, and have this in the
sip.conf file. I had to un-check the "in audio" option, but I've no idea
if the config for the c450's are similar.

If you have another SIP phone (not a C450), you can see if the ##
is working on that first - that would make sure the trixobx system is
actually listening out for the ## code - at least if that worked (or
didn't) it would give you a closer pointer to look at .. (ie. elimiate
the trixbox if it worked, or point the finger at trixbox if it didn't!)
