asterisk users - Feb 2006 - Swapping lines using dtmf

I have a request from a customer to be able to switch lines using dtmf, for
example pressing ** to switch to the second line. So if a user is on the
phone, and they hear the call-waiting beep (which I am alos not sure if it
can be implemented on asterisk directly), they would then press ** to pickup
the second line. The user would then be able to switch back and forth
between the two lines using ** as well.

If anyone has any ideas if and how this can be done I would apreciate any
info.

Regards to all,
Joe

You can search for flash() on the wiki, start here 
http://www.voip-info.org/wiki-Asterisk+cmd+Flash . I hope you have 
better luck than me, I've no gotten it to work yet except by the 
transfer trick, something like this:

exten => _6[0-2][0-4],1,Flash()
exten => _6[0-2][0-4],2,Dial(SIP/1${EXTEN:1},,rtT)
