I don't claim to know much about the SIP protocol, but it's my (possibly
flawed) understanding that Asterisk doesn't interpret an incoming FLASH
message as part of a SIP INFO packet as a request to put the call on
hold or to transfer the call.  And just to be perfectly clear, I
personally don't think that FLASH is the proper way to initiate these
sorts of events in the SIP protocol.  To do a call transfer in SIP, for
example, you should be using the REFER primative.

(And just for the sake of general trivia, I haven't yet been able to
figure out how to get Asterisk to generate an outbound FLASH message
over SIP INFO either.)
