[Asterisk-Users] IAX clients and the flash button

[firedude at shorelinuxsolutions.com]

Hi guys
As usual I am playing around with IAX soft clients.  I was wondering with 
the various IAX clients, IAX client, DIAX, etc how's one park calls, 
transfer calls, etc since there is no flash key?  Is there something I 
must do in the iax.conf or is it something I must do with the individual 
clients?  Also, is it very difficult to use musiconhold with the IAX 
software clients?
Thanks a lot for any ideas, suggestions, feedback.
