Dan, Ariel is asking you to attack this problem incorrectly. You are
correct that there doesn't seem to be a flash function in IAX. There
doesn't need to be a flash function as you can signal out of band.
Specifically for transfer there is these IAX_FRAME_IAX subclasses;
#define IAX_COMMAND_TXREQ       22      /* Transfer Request */
#define IAX_COMMAND_TXCNT       23      /* Transfer Connect */
#define IAX_COMMAND_TXACC       24      /* Transfer Accepted */
#define IAX_COMMAND_TXREADY     25      /* Transfer ready */
#define IAX_COMMAND_TXREL       26      /* Transfer release */
#define IAX_COMMAND_TXREJ       27      /* Transfer reject */

This means you just need to make a software transfer button. 

Of course while your at it, you might want to look into the three way
calling functions, and any other calling functions that might need to be
added that would otherwise be used by flash hooking a zap channel.

Hope this helps.
