asterisk users - Mar 2008 - Dialplan Help

I've got a couple of extensions in users.conf that have both SIP and IAX
access(IAX softphone, SIP hard phone).

I'd like to setup my dial string to "check" to see which they are
actively registered with, and send the call appropriately.

Right now I have:

Exten => _4xx,1,Dial(SIP/${EXTEN}&IAX2/${EXTEN})

But not all phones have both techs, so there is a lot of "misses"

Is there a way to use the hints to see which they are registered with, and dial
only using those channel types?

you can mention the context
and dial plan so that respective users go to the same channels
they belong to
